That wasn't my experience. It gave me about 40 seconds of boost over what I'd normally get out of my concentrators, and during that 40 seconds the oxygen was constantly dwindling, so that my flame grew more reducing every second. Not only that, but I'd have to wait 40 seconds to figure out where the oxygen was actually going to end up after I set it, as the tank took that long to build or release pressure.
Now, a compressor and a tank - that's awesome. Just a tank, though? Garbage.
If you're working small, a Cricket actually will give you a more useful flame than a Minor. The Cricket packs the same amount of heat into a tighter, more focused flame. I'm not a big fan of the Cricket or the Minor, but if I was working on a single 5lpm concentrator, then a Cricket or a National 3a premix wit a 31-hole or 55-hole Shelbo tip would be my choice.
