this product have perform admirably after 6 month of use and counting . I still love my Apple Bluetooth keyboard that come with my imac but it be suck up battery every two week , even under moderate use . this be true of many Bluetooth device . enter the Logitech k750 solar power keyboard and the problem be solve . the build quality be very good with a nice heft to it even though it be make of plastic . the solar power work extremely well . even with a small desk lamp the battery gauge never drop below 96 % . I have go day without put direct light on it and the battery meter barely budge . but the nicest thing about the keyboard aside from the solar power be the feel of the key . type on this thing be a pleasure . it be very soft and quiet . you also get the numeric keypad on the right just like a regular keyboard which be great for I for work . also worth mention be that it work in Windows too , just the special function key on top do not work but for normal typing it be fine . overall , a very nice product and a must for those who do not want to deal with frequent battery replacement .
