While I have no direct experience with this torch set I do have some comments from years of second hand information. These types of solid OX and fuel units have a poor record for frame work. The duration of the OX and fuel is short and the cost begins to add up. I have read reports of not being able to braze a BB or crown before the stuff ran out. Many have posted that they ended up moving on to a standard OA set up. Given the recent increase of propane and O concentrator sourcing of O it seems that the low cost future is in this pathway.

Some of us have been doing this building stuff for decades but never "went pro". If I had made the right choices in my tools right from the start I'd saved thousands of dollars. Andy.
