I had a Lenox acetylene regulator with Gentec torch tips that worked fairly well until the piston bore started leaking enough acetylene to even turn my big tip blue. I was disappointed that the regulator is not more than a year and a half old. This new Harris regulator seems to work better and I love that you can see how much pressure is in your line. The biggest thing I like is how clean and well formed the blue cones are in the flame compared to my Gentec torch tips. You can see that this flame is of the best quality. I only wish I had the set of 5i - 14i
