Logitech K750 Wireless Solar Keyboard for Windows Solar Recharging Keyboard 2.4GHz Wireless - Black

Comment

I bought one January 15, 2016. It has the old Logitech logo on it. It is a 5Star perfect keyboard. I bought another one for my home on May 17, 2017. It has the new Logitech Logo on it. The left CTRL key was rubbing against the cover, and not depressing or sticking down if it was jammed to depress. I returned it thinking it a one-off dud. Amazon sent a replacement. The replace came in. Same problem with the left CTRL key, but not as severe. It clacks loudly when I press it while the other keys are quiet. This problem with the newer models takes this from a perfect 5Star keyboard to a sub-par 3Star keyboard because of the force required to depress the CTRL key and the loud noise it makes and the looseness of this one key. Its a shame really. After months of using it, this keyboard has proven a complete waste of money because some keys still stick or fail to press. Potential 5 star, perfect keyboard is now useless and purchase of this keyboard should be avoided.

I purchased a K800 keyboard for work and at home in 2008. I loved the keyboard, but it had one fatal fault in both places: battery life. The time between recharging wasnt bad the first year, but deteriorated over time and became a constant annoyance. Replacement with high-quality batteries of the same type never restored the original battery performance. After retiring from my career, I decided that the poor battery performance was intolerable for my home keyboard. Since Logitech had no model upgrade for the K800 that offered better time between charges, I opted for the K750, which promised NO charging. I have been very pleased with my choice, and saved some money to boot. After several months, I have not had to recharge the keyboard once. With the K800, I would have had to charge 3 or 4 times. As far as the keyboard itself is concerned, I can find no noticeable differences. Logitech has always had the best key design, which is why I have stuck with keyboards from them for 30 years. By the way, the Solar App that they provide as download and which is activated by a key on the keyboard works very well. My office is quite bright during the day, so the condition of the batteries is always at a high level. I can see staying with this keyboard for at least 10 years.

This is a silent keyboard thats feels good to type on, and keys seem to be durable. Programmable function keys is unique to this keyboard. Function keys can be set to wide variety of commands, keystrokes, actions etc. In particular, programmers will appreciate the ability to set function key as "_". Furthermore, this can be accessed directly without pressing "Fn" key. I strongly recommend this keyboard just for this reason to anyone who is into computer programming. Other keyboards offer very limited options for function keys. Solar power prolongs battery life infinitely, can recharge in indoor lighting. On the downside, the battery or solar charging setup stopped working on my keyboard after about 2 years use. Theres no recourse but to throw away the keyboard. I strongly urge Logitech to improve on this flaw related to power source / supply circuitry. Because otherwise, its a really a great product.

I bought this keyboard ~10 years ago when it first launched. I never regretted for a moment. Unfortunately I had it in my backpack one day and one of the keys broke off. So recently I ordered a new one. The new one had the number pad enter key break during normal use within a couple days (product was used bare in mind). I attempted to transfer the working keycap from one keyboard to other realizing I had 2 functional keyboard, each missing a key, neither of which were the same. I COULD NOT any key other than the standard alphabetic keys to come off without breaking something. Despite having essentially a doner keyboard to mess around with, I still could not get the Enter key or ESC keys to transfer properly. With all that said, I still recommend this keyboard of anything Ive ever used, it is just such a nice keyboard to type on.

Have been using this keyboard for one year (using it type up this review), and it has performed flawlessly. It is left on most of the time; it does not receive direct sunlight, only the occasional light from my desk lam; yet I never had had any battery issues or has it lost charge. Never. To be sure, I have not used the keyboard extensively day in and day out ( no writing of ones lifes memoirs here), only typical daily use surfing, writing e-mails, working on spreadsheets, etc. Never an issue. Some people ding this keyboard for lacking LED lights for Caps Lock and Num Lock. While true, it is hardly an inconvenience. Indeed, if I do not know what the status of the Caps Lock is, i.e., enabled or not, all I need to do is tap on the key. A big box pops up on the screen telling you what the status is: Caps Lock On or Caps Lock Off. The same for the Num Lock key. That is to say that for me, not having these status lights on the keyboard is pretty much a so-what. I also have seen comments regarding loss of function or keystrokes not registering on your computer. While true functional problems may exist, the instances when situations like that have happened to me, although not with this keyboard, is because your USB Bluetooth receiver is probably plugged in right next to or in the vicinity of a device that causes interference at the Bluetooth frequency. Check around your PC to see what else is plugged in. This has happened with my wireless mouse. It is not the fault of the device; it is just a matter of eliminating the interference. This is the bottom line for any review: Would I but it again? Absolutely, without any hesitation. This is one great, amazing keyboard. Love the full layout as well.

This is the 4th one of these keyboards that I have ordered. I love them for work, and for gaming. The soft touch keys are super responsive. The batteries do seem to wear down if you dont have optimal lighting conditions, or if you forget to switch the keyboard off during latent or unused periods. You can order replacement rechargeable coin type batteries on different sites. There is a tendency for buttons to get caught and pop off, and then you need a professional tool to put them back on as they are secured like laptop keys. You need to be careful also when transporting for portable use that the legs under the keyboard do not get caught up as they will rip off, and then most of the time you can put them back on.

The single best keyboard I have ever owned. I have had this keyboard for several years now, and cant imagine using any others. It works flawlessly every time and receives plenty of charge, even in my low light bedroom. I have to keep a steady supply of AA and AAA rechargeable batteries on-hand for my other devices (remotes, mice, trackpads, etc.) But I never have to worry about such hassle with this keyboard. I wish everything could be this low maintenance! The key feel and layout are perfect for this touch typist, not too stiff, not too mushy, and a good throw. Being an old-school Windows user, a keyboard isnt complete without a separate numeric keypad and navigation sections, so that was a requirement for me. My only wish is that they offered a Bluetooth version since ultrabooks have a paucity of USB type A ports.

Absolutely the BEST keyboard Ive ever owned. As a programmer, I am quite picky about keyboards. Ive probably used dozens of different keyboards over 30 years, but the K750 is the most comfortable, productive, responsive and practical keyboard Ive ever used. I know keyboard preference varies greatly from user to user, but everyone Ive recommended this keyboard to loves it. Besides usability, not having to change the battery EVER is icing on the cake. It just feels right when you type on it from the key height to the tactile feedback to key spacing to the key layout. It fits nicely in a laptop bag and has an easily accessible on/off switch so you can clean it without random keystrokes being sent to your computer. Are there additional features I wish it had? Yes! I wish it was backlit. They would have to accommodate 6 star reviews. :) I wish it had dedicated multimedia buttons, but then the key layout may change. I wish it had a wrist wrest, but then it would be bigger.

Things I really like about this keyboard: --The keys have great feel. Its like typing on a nice laptop keyboard. --Theres no built-in wrist rest so I can use my own gel wrist pad which I prefer. --Its light. --The keys arent too close together like on some other wireless keyboards. Things I dont like: --There seems to be some quality control issues with this model. The first two I received from Amazon were defective. On one of them the "U" key was partially detached, and on the other the control key didnt work. But they replaced the keyboard both times and the third one works perfectly. --The two little extendable feet which hold up the keyboard in the back feel REALLY flimsy and Im worried theyll snap off at some point. This is a great choice if youre looking for a wireless keyboard that has a nice feel, but is also light and doesnt take up an inordinate amount of space. Re: the solar power feature, I use it in a room with normal lighting and I never have a problem with the power.

It requires a bright light shining on it for it to be breaking even in amount of electricity being given over being used. This becomes a hassle because I constantly have to worry about that. Once I forgot to turn it off and when I came back, it ran out of power. As a result, I have a led lamp shining on it whenever its in use. Disconnections happen. Even in the best situations, there is a tiny delay between typing and the keyboard registering the keys compared to a wired keyboard. At worst, theres no connection at all. This happens about every hour. In between that, therell be spasms where nothing shows on the screen and then all of a suddenly it all rushes out. For any gamers out there, its nearly impossible and extremely frustrating. The low profile, scissor keys are nice. I prefer it over all the others that Ive tried, even over mechanical keyboards, but its just those few times where Im typing something else and all of a sudden nothing appears on the screen. Its a good keyboard for light use where you dont require that much typing.
