I love my keypad, which I bought for data entry. I chose this brand because it was affordable and compatible with both my iMac and PC netbook. I am impressed with the quality and don't mind the key positions. In fact, for me, the relation of the tab, backspace and enter keys are perfect for quick data entry--so much so that I even plug it in to use on my PC desktop in place of it's standard keyboard! I just purchased my keypad, so I can't speak on the durability of the product, but it was a great investment for me!
