Once it was working, it was fine. Strange way to do the velocity though - using the up and down arrows on the back, I believe.
Honestly? Don't spend the money on it. Get an Etek4 + .50cal kit.
The regulator is in the grip, so it's a standard clockwise/counterclockwise rotation with an allen key, not up/down. It shares much of the design principle as the 09 Impulse in that regard. I would venture a guess and say that someone at your shop was messing around with the gun and had the reg opened all the way up and just over-pressurized it.
Essentially, the Nano is a fancy macroless .50 Ion. It'll be the best feeling/shooting .50 gun, that's for sure. Should be about as reliable as any Ion/Extcy/whatever other iteration of Ions there are.
