The keyboard does connect and work as advertised with my Axim X51v. However, after only occasional gentle usage over something longer than a year (perhaps used 10 times in the library) the bracket that makes up the PDA stand snapped in half due to its support wire, making the PDA support useless and closing the keyboard difficult. Customer service said since it is out of warranty my only option is to purchase a new keyboard since they don't make parts available. Does it work? Yes. Will it last? Probably not. Not many other options out there, but be aware this is a very fragile device that, when it breaks, can only be replaced and not repaired.
