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.
After dropping my old wireless too many times I needed a new one. I found this one that works great and I love the lights. it works perfect and if I need light on my keyboard it helps too. Auto-off saves battery life as well.
