Logitech MK750 Wireless Solar Keyboard and Wireless Marathon Mouse Combo for PC

التعليق

I would have given this wireless Keyboard Mouse five stars if it was not for the intermittent LAG I have been experiencing. Sometimes, but not all the time, the keyboard acts like it is late to dinner at waking up. Then all of a sudden it works but misses the first keys sent. Or worse, a key gets pressed and it wakes up in the middle of that, and stays pressed until hit again. I moved the USB dongle all over the place. From the front of my PC, to a USB hub, to the back of my PC. The issue continues. I thought maybe it was my phone or other RF interference but I am pretty sure I eliminated all that with no results. So perhaps I have either a bad keyboard or dongle. The solar app shows the keyboard is fully charged so that cannot be the issue. Strangely, the mouse seems unaffected. I have several unifying dongles I bought as a back up in case one gets lost, so I will try to pair with one of those to see if this fixes it. As for the product itself, when it is working, the action of the keyboard is (for lack of a better word)... beautiful. I do not think I have ever typed on a nicer keyboard. It reminds me of the keyboard on my laptops, but nicer. The mouse feels a little flimsy but has not failed to perform at all. The rigid/smooth mouse wheel button feels a bit clunky, but honestly, how often is anyone going to change that preference? I guess if you are a graphic artist you would. It is also much lighter than I like. My M510 is much heaver and I like that in a mouse. In my opinion, the intermittent keyboard thing has to be either a software bug, driver issue, or maybe just a dongle issue. It is hard to low rate this combo because of it, considering how heavy the keyboard is (NICE!), how solid it feels, how great the action is, and the layout. And even the solar app works great! Over the top maybe, telling me what the LUX is when all the time since I had it, the battery has been 100% charged. Unless you are a vampire that needs to compute in complete blackness, one would never even have to look at this app. Still, it opened my eyes to this application and how it can be applied to other embedded projects I am building. This is why I am resisting the urge to take this baby apart and see how they did it. :) I will post an update if I figure out what the issue is with the keyboard lag. One late note worth mentioning. Just unplugging the dongle and plugging it back in fixed it for me, at least for now. If it comes back, I will rinse and repeat. If it continues to make it work for awhile, then at least I know where to go to continue troubleshooting.

So pros are that its a keyboard you never have to recharge, keys are relatively quiet, and you only have to use one USB port for both the mouse and keyboard. Cons are that the keys do get glossy with heavy use (but thats no different from any other keyboard nowadays) and that the keyboard is very low profile so its great for casual use but with heavy typing you do have to really focus on keeping your wrists straight. The mouse is great, has more buttons than I know what to do with haha but thats a bonus because as I learn to use them I can work faster. Only drawback so far as I can tell is the scroller slash third key is really easy to actuate which can be a problem if you use blender or other software that requires you to use that key often. Overall extremely satisfied with the product.

I got this keyboard about 3 months ago and have been using it everyday since then. Pros: No need to replace batteries! Easy set up Durable materials Quiet keys Price Cons: Sometimes the keyboard freezes and I have to turn off and on to get it to start typing again. This is the reason why I gave it 4 stars instead of 5. Its not a big deal but I dont think it should do this. Other than this its a great keyboard. Theres an on and off button. I always leave it on and have no issues with the way it charges. I love that it has a button where you can check if you have good lighting for proper charging. I dont have this keyboard by a window, plain office lights do the trick. I saw some folks complain about the solar bar scratching. I decided to leave the plastic that protects it and dont even notice it. Overall I recommend this keyboard.

Ive had four of these. On the first one, one of the keys started failing after a year of light to regular use, so I replaced with the second one, where I spilled coffee on. It did get soaked but still worked. However because the keys became sticky I hosed the keyboard, yes I did and dried it out. It didnt work after that. It could be because I did not remove the battery first or did not turn switch off (to turn the solar panels off). I threw it after that not even thinking to replace the battery first. well thats all on hindsight. I am on my third one on my home PC and have a fourth one at work. Only changed the battery on one but I think it was unnecessary. It was probably because I let it drain and did not have enough light shining on the keyboard. Other than that instance, I never had to replace batteries on the rest of them, and its been years now. Should be 5 but that meant perfect, but because of the failing key i knocked it down a bit. Maybe it should be 4.99 ?

Ill jump right into this by reviewing both parts of the combo. Mouse: Without a doubt the worst mouse I have ever used. The scroll wheel feels cheap and is WAY too sensitive. It has a button to change it from a smooth operation to a more feedback oriented motion which is pointless, I mean since when did you ever need smooth scroll wheel operation anyway? So often times when you click down on the scroll wheel, your page will move up then activate the scroll wheel button which is HORRIBLE in games or anything that uses the middle mouse button. Secondly the forward/back buttons are in an awkward position which causes you to actually move your hand to press them which is annoying. Outside of those the mouse is fine, but the above is REALLY bad in my opinion. Keyboard: The keyboard is solid. The solar charging works really well, it doesnt even need to be in direct light to charge. Its small which is also nice and keyboard presses are quiet and smooth. Only downside to the keyboard is the gloss coat it has will collect fingerprints like nobodys business. Also the keyboard has no ergonomics to it, its pretty standard rectangular shape. I didnt buy it for that but those looking for one wont find it here. Overall: Keyboard is great, the mouse however is garbage. If possible buy just the keyboard and get a separate Logitech mouse that supports the unifying receiver, any mouse aside from the one in this combo. I personally went with a MX mouse as they are always pretty solid. Battery life on both seem pretty good however, but again the mouse just isnt worth getting the combo so shoot for just the keyboard.

This is the third Logitech Wireless Solar Keyboard I have owned. [Unfortunately, the first one died on me when I spilled a large can of soda on the keyboard and I was never able to get it to work reliably afterwards.] However, I missed the low profile keyboard and the ability for me to pound out more this style of keyboard than any of the others I own or have owned. In fact, I purchased this latest one to allow me to move my older solar keyboard to my other computer. Being able to rely on solar power is a real plus, and to be quite frank, the benefits of the low profile and my typing speed on this keyboard plus the solar power makes this a winning combination in my book. I have purchased and owned many other keyboards but have to admit this overall, these keyboards are by far the best investment I have made (and this is written by someone who spends many, many hours each week at the keyboard).

I just got this keyboard/mouse combo yesterday and functionally, both products are performing well. The reason for the poor rating is that there seems to be a manufacturer defect near the solar panels. There is something causing a bulge underneath the keyboard surface which makes it so that the F6 and F7 keys are no longer flush and that there is a gap between the glass and casing of the keyboard. (see photo) The keys also make a louder click than I would prefer, but that would not have been a deal breaker on this product. The mouse works great though.

I really liked Logitech products... and Im using the keyboard to type this... so far it works, since it came 2 hours ago. BUT WTF!!!!!!!! the damn mouse stopped working in the first hour out of the box. I bought another combo set and the keyboard stopped working in a few months. Now I have a mouse from 1 set and the keyboard from the other, but it does not unify the old mouse. Just plain bulls***. I may stop buying logitech products anymore after this. The keyboard seems nicely made, it charges quickly in room light, and the mouse seemed solid but lost its link and would not sync up after an hour trying. Wheres the quality control? EDIT: I was given a replacement for these items. I will see if the first set of mouse batteries actually last 3 years, and if this mouse/keyboard will last longer than the battery life advertised. I like the keyboard and mouse. They are solidly constructed, and have good feel. Edit: I applied for a refund, and they offered to send a new unit before I send back the defective set... It will arrive in a few days... If this has ANY defects, Ill be getting a refund. So, I added another star for fast service. I shall soon see since the first keyboard of the other set only lasted a few months.

Have only had this a couple weeks so can not speak on longevity, but I love it so far. The keyboard freed up space on my desk. the mouse is very user friendly/ it has a metered scroll and also a free scroll that is great for reaching the bottom of pages fast. The keyboard already had enough charge to start using it right out of the box. To give it it/s first good charge I put my desk lamp over the solar bar and its been going non stop. I admit I forget to turn it off most times but it still keeps going. Very easy to set up. Keyboard is comfortable to work on and has a great "feel" to the keys. The solar capability is very accommodating to even limited light accessibility. I have my keyboard on a slide out desk top that hides it when Im not using it and I had reservations that it might not get enough office light even when Im using it unless I pulled out the tray all the way. It is sensitive enough that it captures enough light without my having to be ultra conscious about it. The downloadable Solar App is a great idea and gives you a quick monitor of your light conditions if you have any question. The mouse is a nice ergonomic design and has a quick response of use.

This is my third purchase of this product. One for home, one for work, and one to replace the lost keyboard from my luggage traveling last year. The keyboard is solar powered which eliminates the need for large batteries resulting in a thin and sleek design. The solar keyboard recharges itself in almost any environment. I have a lower lit room and yet I have never had to worry about the charge in the keyboard. I am also a specialist in office ergonomics. This keyboard, when used properly will lie flat and allow you to type with almost no bending of the wrists. The mouse, though it uses batteries, is very energy efficient. This is one of the best keyboards I have ever used.
