I have had only two compact keyboards, but this one seems to fit the bill. The key response is rapid, the battery life is decent and the overall feel of the keypad is good. Downsides include flimsy if not on a solid level surface, non-intuitive power on and number placement (one key off).Be careful to read instructions when first opening. It could be easily broken if not done properly. Loaded software on AXIM X50v and it worked brilliantly.Overall, I would certainly recommend this for someone who needs an occasional collapsible keyboard. I use it a couple times a week. If you needed it a couple of times each day, I think it would quickly fail mechanically.Oh, and one last thing. Who ever is responsible for placing the sticker with non-release adhesive across the keyboard should be the person that has to come to my house and peel it off with their fingernails - you idiot!
