the good point of this product have be touch on in other review . I will not rehash they here . I own this keyboard for approximately 3 month . it operate well , although I do have problem with the amount of desk real estate it require - it be a large keyboard . this be a minor issue , however . the main problem I have be that one day the number key refuse to work . it be not a software issue , as I have try it on other computer with no success . I have own other Logitech product and they be nice until they break after a few month . I have buy 2 headset , this keyboard , and a mouse that periodically glitch on I from Logitech . with the shoddy performance I have experience I can not recommend they product to anyone .
