I have one, bought it at a farm show. It does take a little practice, but it works OK-biggest thing is that it feels so much different in your hand after using a regular torch.

Having said that, I never use mine anymore, I got a plasma cutter and went back to the regular torch since all we ever use it for is heating something to loosen or bend-the Cobra doesn't make a big enough flame for heating something. I would sell mine reasonable if you are interested, email in profile is good.
