Seemed to work ok, the "inflate" button sticks a tad, slow to release. You know about these though?? How do I take it apart? Seems like a little grease or maybe sanding?? would fix it. I know I can get a new one for $25, but if I can get it to last 2-3 dives before I have to replace it, I'd be grateful. I'm gonna have to pay to get a reg serviced, and a tank hydroed. I got the reg setup (US divers Conshelf XII first and second stage) for $20 (needs a new SPG, but I just bought one used for $50), and the tank for the same. As soon as I can afford it, I will replace the inflator.
