[PF]Tinker (3rd Party Class): Any Experiences?

[Amphetryon]

In mulling over contingency Characters for a PF campaign with a particularly martial party composition, I found myself strongly considering the Tinker Class, from Interjection Games, as represented on the PFSRD. Have any Playgrounders used the Class? If so, were the experiences good, bad, weird, or indifferent? What, if anything, did you like about the Class in play, and what, if anything, made the Class challenging to play?

Looks like nobody has 1st-hand experience with the Class to share. Ah, well.

Well, a member of the high-powered gestalt campaign I'm playing in is playing a Tinker/Time Thief, and to be honest, he's kind of useless in combat. His damage very frequently doesn't get past damage reduction, and his drones aren't super effective.

However, he's incredibly useful out of combat. Then again this is probably a bad gauge, as the game is laughably unbalanced, so take this recounting with a chunk of salt.
