I just got this tank and went shooting around. It wworks great.....light.....consistant and the laser engraving looks good.... I experianced no shutdown during rapid fire like others have posted. I got the whole rebuildable reg so it all works fine.
The only bad thing wa that I had one of the bad tanks for say. If you consider having a bad burst disk thats all I can really think of.
In my option t is a great tank I like it and it works fine. It might be because of what kinda gun I'm using but, get this tank
