Query: Bad Design & Poor Manufacturing Quality

The unit was a gift. I started using it some months later, after it was out of warranty. On the very first project, it started leaking air at the regulator/switch assembly and would no longer develop pressure. The design of this assembly is very poor. I can see why the factory was not able to assemble it correctly and the reviews are so low (more 1s than 5s). Out-it-goes. No Bostitch purchases for me. I got a Husky, no problem.
