This review is from: Logitech Certified Refurbished K750 (920-002912) Wireless Solar Keyboard - Black

This is a very nice keyboard and is very comfortable to type on. The solar thing saves you money but do not buy if always in the dark!

I don't get three months in the dark. I used to be in the dark until I got a new desk lamp and once it hits 40% it starts to lag and skip keys.

I suggest only if you are in a good lighted source for some of the time.
