Summary: Bought this from a major wholesale company about a year ago. We really loved both the mouse and keyboard and felt it was worth the money spent. Recently, though, the mouse has started acting up. It'll navigate the cursor but won't select anything. There's no clear solution. Sometimes we have to turn it off & on, unplug the USB, just wait a while, do nothing - all of the above work at various times and fail at others.
Summary: Great keyboard, EXCEPT FOR THE ENTER KEY ON THE KEYPAD. I've tried two of these keyboards, the enter key broke off of both of them. It's the main key that I use throughout the day at work with the system we use. And it's not like this happens after a year or two, it happens after a month or two. Unfortunate, because otherwise I really like it. Going to try the K800. But this one is their only solar keyboard, which I really like.
Summary: I've generally liked this keyboard for the just under two years I've owned it, even though it doesn't have a Caps Lock (or Num Lock) indicator, which is an unbelievably annoying design oversight. But now the battery won't hold a charge for more than a day or charge to more than about 95%, even if I leave it in direct sunlight for hours. If Logitech would add indicator lights and a decent long-life battery, this would be a killer keyboard.
Summary: I bought this keyboard because the idea of never having to charge it or replace batteries seemed naturally appealing. The keys are very good and it is very comfortable to type on and I also liked the array of secondary functions on some of the keys. However, that's where the good points end. The keyboard drains the battery faster than it should, even in a well lit room. It also charges slowly and VERY inconsistently, again even in a well lit room.
Summary: It does what it says as far as not needing a battery, I had no trouble with it working and holding a charge. The keyboard however has lots of problems. Primarily is the shoddy workmanship and quality of the keys themselves. I took it right from the box and set it on my desk. The first day the plus sign key came completely off. Although It fit right back on the materials seem very cheap. Also the 1 button became stuck somewhere in the first week.
Summary: Bought the keyboard, in Jan 2011, to use in the office. When I received it, the '2' key on the num pad would not work. I contacted Logitech and they sent me a new one. Jump ahead to Aug of 2013, the left 'Alt' key stopped working. Now, November, the keyboard wont work at all. You cannot replace the battery, so I'm stuck with a dead keyboard. Skip the solar power gimmick and buy a replaceable battery model.
Summary: This is my second solar keyboard purchased from Logitech. I absolutely loved the first one....that is until it broke after the first year. Unfortunately I did not have a receipt and was unable to return it. I purchased a second solar keyboard and found it to be extremely loud when typing; very much unlike the first solar keyboard I purchased. Needless to say I was very disappointed with the second purchased solar keyboard.
Summary: I am a medical transcriptionist and have come to love Logitech keyboards. I have to have a new one about every 6 months. I bought the solar keyboard this time because I liked the low profile keys and quietness, but I absolutely cannot keep it charged for 8 hours and sometimes more per day. It is fine for other use, I suppose, but not for my needs.
Summary: Yes, I *loved* my solar keyboard. The sleek design is great, and it was just perfect. However, it died on me after 9 months of use - I'm probably going to go back to the store and see if they will give me a replacement (while I know it will probably die in a few months, too). If not, I'll be stuck with a keyboard that is too big, clumsy, noisy AND needs a stupid wire, too. If you guys could come up with a RELIABLE wireless solar keyboard I'd be tickled pink to own one.
Summary: I have three of these solar keyboards. One in my office, one in my home office, and one in my den for use with a home theater PC. The two in the offices work great and have never experienced problems--the catch is that the offices get a lot of sunlight, the den, not so much. The den keyboard would have to be recharged by placing it under a light source or next to a window. The office keyboards never displayed a low charge.
