Title: Portable but not very responsive
Review: This item was purchased for me by my former employer for ergonomic reasons. The keypad is versatile to be on either side of a keyboard but the keys are not very responsive. As it turns out, I end up having to rekey (more often than not) numbers because the initial keying doesn't register. This adds to more reptitive motions due to the rekeying of numbers. Not sure of why, but I'm about to give up on using this thing and return to a regular keyboard. Their articulated keyboard is very good.
Is the review positive or negative?
