    Rated 4 out of 5�by Key Board Review I purchased this as an alternative to the traditional keyboard and cover. Works well, but limited in application for portability. September 8, 2015
    Rated 5 out of 5�by Clean Up What a great way to get rid of wires. One of the nicest thing to happen to my computer. August 31, 2015
    Rated 4 out of 5�by Nice keyboard It is a great keyboard. Wireless, light weight, easy for use. I only missing the number keys at the right as normal keyboard. August 7, 2015
    Rated 2 out of 5�by Not useful to me Would not recommend it, because most of my friends are ham radio operators and the "F" keys do not work what we consider as normal. To make them work normal we would always have to use them in concert with the function key. I found another manufacturer's (JellyComb) keyboard that was of the same size - small that works wonderfully. Other than the keys not working "normally", the keyboard was good. August 3, 2015
