The same company that sells the milwke has apperently heard the problems and fixed some of them witha slightly higher priced unit they are calling the Top gun.
"Our Top Gun regulators begin life as a MA957(milwakee), we add a new bubble counter that has a built in check valve. We also have added an O-ring to an area that has a tendancy to seep Co2, this makes that unit much more effecient. Each unit is calibrated for accuracy and tested for 1 hour to ensure NO factory defects. Each unit carries a full factory warranty authorized by Milwaukee Instruments. After thousands sold, we have had ZERO units fail.
We know for a fact that some regulators on the market are experiencing a failure rate of 1-2 units out of 10.
FEATURES:
-Dual guage (with tank volume & flow)
-Fully adjustable flow knob (0- 100psi)
-Solid brass needle valve (for precision adjustments)
-Electric "on/off" Solenoid
-Bubble counter
-Built in check valve
(If you have any questions about Co2 injection systems, don't hesitate to email or call. (6 month warranty)
Choose for yourself: We sell: Milwaukee and JBJ and this "TOP GUN" regulator.
NOTE: There has been much debate and confusion about regulators recently...The JBJ has as "built in check valve" but NO adjustable flow on the reg (other than the needle valve). The Milwaukee has an adjustable flow, but NO built in check valve".
JM- just thought I would add this note- I have not used either the JBJ or the milwalkee, and can not tell you whether having a check valve or the extra valve to control flow are worth it- for the extra 15 dollars though I am seriously considering the added feature. STanding by fo more feedback in this wider forum.
By the way for those of you drooling to get in on a calcium reactor building party, like that that is occurring at Washington Area Marine Aquarium Society WAMAS club- even those of us in the area are on a waiting list- they have legitimately restricted it to 12 members for logistical purposes- SO it is a popular event that many clubs could mimic.
