I would NOT recommend to my worst enemy the Mallory that I bought a few years ago. It leaked like a sieve, called tech and they said just put on new O rings and sent me a set for $20. Did nothing so they said ship the regulator with new O rings and two to four weeks they would ship me a new one. I expected they would send me a new one with an apology. I bought a Kirban and no leaks or any other problems. Moral of my story either go with Kirban or take your chances!!
