We had one of the "swing" tube design with ignitor in the middle of the tube given to our program for students to use. Lasted about 2 months then developed a leak. Student got pretty excited seeing flames come out so close to his hand. Don't think I've ever buy one.
i have always used a turbo torch well for as long as i can remember and i love them and all mine have the ignitor in the middle its the only kind i buy, never a problem, now however thinking of also haveing an oxy&accet set for things like RV and TXV'S but as for comps and most common leaks i love my turbo torch
