Logitech MK545 Advanced Wireless Keyboard and Mouse Combo

التعليق

I have owned a few different Logitech accessories over the years and loved them all. Have owned this keyboard and mouse set for over a year now and LOVE IT. Never had any problems with it. Functions as it should and does it well. Batteries last a long time - as advertised (but depending on actual use). The buttons on the keyboard are soft, precise and fairly quiet. The mouse controls feel very precise as well. The clicks are short and distinct and the scroll wheel feels smooth. There is an LED light on both the keyboard and the mouse that warns you when the batteries need replacement - very handy. The keyboard has an adjustable tilt by moving the rubberized feet. You can also stand it on its side and let it stand at a 90-degree angle to give you more desktop space. The keyboard also seems to be spill-proof as it is has a few slots on the bottom for the liquid to drain through (see pictures). Range: I sometimes use this set with my TV while the PC (connected via long HDMI cable) theyre connected to is in a room about 15 feet away and works without interruptions. Overall, a great set and a good price that lasts and is backed by a good brand! Go Logitech!

--------------------------------------UPDATE (March 21, 2017)------------------------------------- I have now received the replacement warranty keyboard. The warranty process was not difficult to initiate, though there were some hoops to jump through and it took a while. Logitech was pretty good about following up during the process as well. Kudos! The replacement keyboard appears to be of similar manufacturing quality as the previous one (see items 1, 2, & 6 from the original review below). It is clear to me that the original manufacturer of the this product for purchases made in 2014-2015 is likely not being used anymore, but Ill give this replacement keyboard a chance. Perhaps the last one was just a "dud." In summary, I recommend this keyboard based on the design (look and feel is great), but caution any buyers that you may run into issues within several months. Again, Ill update this review in a few months to let the Amazon community know how this replacement keyboard is performing. If this keyboard ends up being fine after 6 months, I would say that my experience may have been an anomaly. However, if the same thing happens, then there may be a systematic problem. Stay tuned! --------------------------------------UPDATE (March 9, 2017)------------------------------------- As of March, 2017, the keys on the keyboard are now failing and require more pressure to push, resulting in many missed characters and more typos. Im incredibly disappointed... Amazon has NOT responded to my original inquiry, but I contacted them today by phone and they were more helpful. They suggested that I contact the manufacturer and file a claim against the 3 year warranty. Also, I now think that a more likely scenario than the product being counterfeit is that Logitech changed manufacturers or reduced costs in some way. Unfortunately, their cost reduction has resulted in a lousy product and tarnishes the Logitech brand name. I no longer blindly trust the Logitech brand with regard to quality. I will update this review once I know where Logitech stands in regard to customer service and honoring their warranty. One last thing: The item in the Amazon photos is not identical to the product I received. -------------------------------ORIGINAL REVIEW (November, 2016)------------------------ I believe the product that was shipped to me was COUNTERFEIT and not actual Logitech. I have purchased this same keyboard made by Logitech for multiple computers and this one is different for several reasons, albeit it looks pretty close: 1. Keys are made of coarse plastic (not smooth) 2. Logo looks wrong 3. The mouse is already falling apart after a month 4. Keys dont press smoothly 5. Range is much poorer than previous ones Ive owned 6. The paint on the keys is clearly poor quality I have an open inquiry with Amazon regarding this item/seller. It is possible that Logitech decided to save money on costs and reduced quality, but the item doesnt feel right. Will update review accordingly. Thanks!

I bought my first MK520 set a couple years ago. The mouse and keyboard both worked great until recently I noticed my left mouse button wasnt working properly. It would register single clicks as double clicks and wouldnt always register when I was performing a long press. Because I was still within the warranty period I contacted Logitech and requested a replacement. After providing proof of purchase from Amazon, Logitech sent me a brand new MK520 set. The warranty process took about a week -- all by email -- and was easy and painless. I was very pleased to see Logitech stand by its product and send me a replacement mouse and keyboard even though my keyboard was still working perfectly. Now that I have the new set, I am enjoying this product even more. The latest version of the keyboard has different keys than the set I had previously. The keys feel a little more "gritty" which allows my fingers to grasp the keys better. Not much changed about the mouse, but it was already adequate. Wireless signal strength is still great and never was an issue. Battery life is much better than the cheaper Logitech set I owned several years ago before my first MK520 set. Overall I am very pleased with this product and would recommend it for anyone looking for a decent keyboard and mouse at a reasonable price. Also and most importantly: if you run into any problems or defects with your keyboard or mouse and youre within the warranty period, contact Logitech! They will work with you to rectify the issue and will send you a free replacement if need be. (Note: one star was deducted from rating because the first mouse failed. While Logitech did a great job resolving the issue, the fact is that it still occurred.)

Ive been using this set daily for about 6 months now. I loved it at first... but have begun to have major response issues with both the keyboard AND the mouse. Since I work in graphic design and often need major precision... this is a big problem. It will just freeze up & then be ok, and freeze up again. As other reviews have said, the keyboard occasionally has lag issues and the shift & ctrl keys struggle from time to time. The USB is not too far away, and I have also tried fresh batteries. :( I guess this set is not as good as I hoped. Revised my original review from 3 stars to 1 after a few more months of use. The keys got slower to respond, prone to freeze-up and super frustrating. Im really over it. In order for me to continue working, I had to switch back to a plug in set.

Ive been looking into keyboard and mouse combos for some time but I hate that most come with a compact mouse. When I saw this pop up I knew it was the one for me. My previous HP wireless mechanical keyboard was loud when typing, and I type quite a bit with practicing my programming and web development. This keyboard is quiet and the feel of is similar to that of a laptop keyboard, only with more key travel. If you have used the K800 keyboard, its the same type of soft, springy feel to it, only this one isnt backlit (not too important anyway since that kills battery life). The mouse is comfortable and slides nicely along my wood desk. Clicks from the buttons and scroll wheel are quiet yet tactile. The pictures make it look like its black in color but both the mouse and keyboard are a dark gray! Not bad looking in my opinion. Overall, its a great combo. Especially since it comes with a full sized mouse. Other combos will cost you more. Pros: -Quiet! -Nice textured finish on the palm rest -Caps lock indicator -Shortcut keys for sleep and settings is nice -3 levels of height adjustment -Unifying receiver. Cons: -Volume key response did not seem to keep up as well as my HP keyboard when tapping it quickly. -A better battery indicator might have been nice. No biggie.

I use my Logitec wireless keyboards even in installations where conventional keyboards were adequately serving the purpose. One doesnt realize what a nuisance keyboard and mouse cables were until one finally goes wireless. These units connected immediately to everything: Windows desktops and laptops, Linux desktops, and Windows tablets. One of our applications uses a Windows 10 tablet connected to a 60" TV. The tablet is beside the TV and is controlled by a Logitec wireless keyboard/mouse combo from across the room. With a tap on the TV remote, my daughters family can switch from cable tv to big screen computer. Their living room has become a theater for viewing movies, Facebook sites, and emailed photos. It can also be an on-line classroom for their homeschoolers. Family Movie Night, thought to have been killed off by the advent of portable viewing devices, is alive and thriving in my daughters nine-member household, thanks in large part to the versatility enabled by a $140 tablet and a $35 wireless keyboard. Money well spent.

Bought this to replace an Anker keyboard/mouse set, also wireless, that had serious lag issues in time it took for keystrokes to register on screen. This combo from Logitech works flawlessly. The mouse sensitivity was great right out of the box (I realize its adjustable in Windows as well), and the keyboard has a quality look and feel, with a very micro-pebbly, matte texture and great key shape. I think they refer to the key shapes as chiclet which is appropriate, as they have rounded edges that prevent inadvertent striking of the key next to the one you are trying to strike. I type pretty fast, probably 60 words per minute when really going, and this keyboard keeps up no problem. There is one USB receiver for both the keyboard and mouse, which is nice as it doesnt take up any more USB ports than needed. Mine is plugged into a desktop about two feet from the keyboard and three feet from the mouse - no transmission issues whatsoever. Keyboard also has some interesting shortcut keys on the function row, I havent explored them all but I did notice (and appreciate) a calculator key that launches the Windows calculator when pressed. I didnt know I had a Windows calculator! All in all very pleased with this purchase - reasonable price for well above average quality.

Knowing that we all have our preferences for keyboard touch and feel, I have to say that I love this one which arrived an hour ago. Keys are slightly concave. Noise is quite moderate, just enough to know that I have hit the key. Not only does the Caps Lock key have an on/off light in the key itselt, but it is intuitive. If I start to type my name using lower case, it automatically capitalizes the J. All of the keys work. I like the comfortable wide hand rest below the keys. The mouse glides very smoothly, feels comfortable and works perfectly as far as I am concerned. My computer is in a cabinet with a wooden door about 30 inches away but no problem "hearing" the keyboard/mouse. I tried moving the keyboard 8 feet away, still no problem. Setup took less than 5 minutes. With pre-installed batteries it was just a matter of plugging the tiny receiver into a USB port on the computer, turning the keyboard and mouse on, and away we go. I should mention that I put out a question on whether there was a caps-lock light and got both yeses and nos, but the keyboard I received on 9/13/17 has the light. And I get zero delay, hit the key and the character appears instantly.

I like the full size keyboard. I have it only 4 stars for the following reasons: 1. The keyboard requires AAA batteries. There would be plenty of room for AA batteries and I would expect that battery changes would be far less frequent. The mouse takes one AA battery. Thus you need two sizes of batteries to keep this puppy running.2. The keyboard has an ON/OFF switch, which is fine. But what dweeb thought it ought to be located on the underside of the keyboard, instead of the top? Perhaps the dweebs at Logitech could explain why its better to have the switch on the bottom and out of sight with black raised letters on a black background to indicate the switch position. The mouses switch is also on the bottom, which I can sorta understand, but it has contrasting labeling of the switch position. and 3. i HAD A LOT OF PROBLEMS IN THAT THE KEYBOARD, AND SOMETIMES THE MOUSE, SEEMED TO BE VERY SLOW TO RESPOND. TURNING THE KEYBOARD IN AN UPRIGHT POSITION SEEMED TO HELP. iT WAS SO BAD i HAD TO GO BACK TO WIRED KEYBOARD AND MOUSE. THOSE WIRES DROVE ME QUICKLY NUTS. I REALIZED THAT THERE WAS SOME INTERFERENCE ISSUE. AS I WAS LOOKING AT USB HUBS, TO PUT SOME DISTANCE BETWEEN THE COMPUTER AND THE DONGLE, I NOTICED SOMEONE MENTIONING THAT THERE WAS INTERFERENCE PROBLEMS WITH SOME DEVICES USING THE USB 3.0 CONNECTIONS. I SWITCHED THE MOUSE/KEYBOARD DONGLE OVER TO A USB 2.0 PORT AND THE THING WORKS FINE. MAYBE LOGITECH OUGHT TO MENTION THIS PROMINENTLY.

I have had this mouse and keyboard set up for 7 years on a Dell computer. I have just upgraded computers and wanted the same mouse and keyboard to keep my feel on the keyboard the same. And I will refer to the Dell once and a while as my backup computer. So the new keyboard and mouse are working great now. Yesterday not so great as I figured one thing out. I had put the receiver in a USB port directly beside the USB connection for my laser printer. When I was printing, the mouse would stutter, freeze, or disappear. I have a new Duracell battery in it, not the cheap supplied battery. But I was noticing a pattern, and yes, when I typed, sometimes what I typed took several seconds to appear. I now re-located the receiver to another USB port not near the laser printer cable. And mouse speed and typing speed are back to their exceptional fastness. So for anyone encountering the drag problem, get the receiver away from printer cables, or possibly other USB devices. I would think external hard drives and DVD players would not be as big of an issue as a laser printer. But they could be. And for those who actually complain about the noise of the keyboard, yes it makes noise. If no radio or TV are on in the room, you will hear every keystroke. But it is not a loud annoying sound, it is just the flow of your work. The keyboard feels great to use. You get to snap the keys a little and they respond well. A fair trade off for a little bit of noise. And if the noise is a problem, turn up the music a little. The fan in my laser printer next to me is far more annoying than the keyboard click. Better than having to shove your fingers on the keys to get them to respond. 4-10-19 Add on and change to review. I am purchasing another one because very possible this set is a bit defective. Having a problem with the mouse. It seems to be receiving a single to double click or click and drag when I am just single clicking the button. Not a dirt problem, not a battery problem, and I am pretty sure it is not a driver or setting problem. I have tried several times of setting the double click speed both faster and slower. It is becoming difficult to select a block of text with it. So I am replacing it after a year. Just goes to show you that in a production run of products, sometimes you get a good one, sometimes you get a bad one.
