This is a perfect addition to my laptop. I do a lot of work on excel and this makes number crunching go so much faster. The USB chip works like a charm and I've had no connection issues to far. The keypad numbers type just like a normal keyboard and the .000 button comes in handy quite a bit. I would recommend this number keyboard.
Good quality set, has a decent range of operating, volume adjustment nub built in on the keyboard ( you don't need to get up to change the settings), mouse has good sensitivity to touch ( doesn't have to be a mouse pad only, it reacts to the furniture upholstery too)
