Review on Versatile Big Refillable Jewelry Torch with Adjustable Flame - Ideal for Soldering, Metalsmithing, and Kitchen Brazing by Stephen Parkell

I don't normally write reviews but this product exceeded my expectations. The flame is very strong and the longer you use it, the less intense it becomes. This product is suitable for soldering and annealing jewelry. It also has intensity control so you can use it for multiple purposes depending on your needs. In addition, it has excellent durability and is shockproof. I have used it many times, refilled several times, everything works fine. Highly recommended.
