Summary: Great price and meets my needs. I love the fact that you can multi use it... on and off computer. My only complaint is it's very lightweight and feels kind of flimsy The keypad is of reasonable size and quick to get use to.
Summary: I have read many reviews that complain this is not full sized but that is in comparison with the keyboard or pad they are used to. When using a small laptop it is just the extra keys needed to make my entry easy. Be prepared it is smaller than full sized keys but just perfect for what I wanted.
Summary: only part I didn't like is it turns its self off to fast, around 10 min's of not being used it's off again, and you have to turn it back on again, I called kensingtion and they said there is no way to change that.
Summary: I bought this for my daughter who was in a business math class. I thought it would be good for her to get used to "adding machine/keyboard" number locations instead of calculator placement. She loved it and after the class, my left-handed husband took it to work with him and is still using it! Awesome product!
Summary: I think separate keypads are great if you do a lot of spreadsheet, accounting or similar work requiring a great deal of number crunching. With that said the two features that most lack that I think they all need is an <ENTER> key and a <TAB> key. This Kensington combination keypad/calculator does have a small <TAB> key, but NOT an <ENTER> key.
