Users enjoy this item for it heats up solder quickly, is easy to refill and easy to use. The lightweight build of this product has been commended as well, for it makes the overall soldering process easier and more comfortable.

“I love this iron for doing small jobs inside or outside in my truck. The iron heats up quickly and lasts about an hour at full heat. Much easier then running an extension cord outside and bringing my soldering station outside. This setup is portable, easy to throw in a bag and works really well. Very highly recommended.”

Bret, Amazon Customer Review

“I have a couple of these at work, and while I only use them once in a while, the portability factor of this iron makes this something I love to use. It takes a bit of pressure and a steady hand to refill it but it’s not at all hard to do. It heats very fast and as long as it has fuel its utterly reliable.”

Wayne, Amazon Customer Review

“This makes my job so much easier. It comes with quite a bit of tips and even a cleaning station (I don’t use). Butane lasts a good amount of time and I’ve yet to have any issues with lighting, I always click it 3 times to start it (just to be safe) and it never hasn’t worked. Torch function by removing the tip also isn’t half bad”
