First of all it seems that the reviews on this site are for the Bulldog 1 and Bulldog ajdustable regulators. I have the new Bulldog II and this reg. is awesome. I know that ACI used to have someone else make there regs. for them know they make them themselves. My Bulldog 1 had alot of problems and I was having problems with the company that was making for ACI, that is probably why they make themselves now. I have been using it since September 2001 and I have had no problems. I would recommend this to any one that is looking for a good bottle. When you are looking for a bottle make sure that you are getting the Bulldog II and not the Bulldog 1 or the adjustable reg.
I have not found anything wrong with my new Bulldog II reg. and I have been using it for about 6 months. But I did have problems with my Bulldog 1. The threads on the Bulldog 1 were always going bad where you screw it into the gun but they took care of that on there new one.
I would recommend this to any one that is looking to goto compreseed air, It works just fine on my Angel.
