After trying this product I am thoroughly impressed with its performance. As an Automotive mechanic, I have used numerous welding tools and can say that this one exceeded my expectations... The unique open-end design allows for easy access to nuts and bolts in tight spaces. The IDEALFLAME Igniting Soldering Wrench heats up quickly and is very easy to use. The only downside is that it can be a bit pricey compared to other welding tools on the market..
