Purchased it for my friend, he likes it lots, although oddly enough rarely the mouse stops working for like a few seconds
and the keyboard has problems displaying the media on it's little lcd screen
Ideally you want to go wired. Wireless has improved a lot and is fairly reliable now days, but just when you don't want it to, it will act up. In both cases of wired/wireless, go Logitech.
Well i can say that the best wireless and wired mouse would be the logitech g700 gaming mouse
if you dont like wireless just switch it back to wired
problem sorted
