Review: Great Portable Soldering Torch - The Good Stuff * The torch features almost instant gratification. Flip the torch on, press the ignite button, wait about 30 seconds, and you are ready to solder. * The torch puts out a lot of heat. I found it able to solder almost anything I throw at it. * The torch has a built in self igniter. I have never had a problem starting the torch. There is no need to remember matches or a lighter. * The torch has a built in stand feature. This is a handy addition for field work where traditional iron stands are unavailable. * The torch uses standard butane fuel. It has about a 2 hour run time on a full tank. Refills are easy to do and take about a minute maximum. You can use the torch almost anywhere. There is no need to worry about AC power or cumbersome cords. The (Not So) Bad Stuff * The exhaust port on the torch near the tip gets very hot. You learn very quickly to point the exhaust port away from your fingers when soldering equipment. * The torch puts out a lot of heat. Monitoring is needed to ensure the tip does not get too hot during usage. * The torch uses standard butane fuel. Butane refills cost money. The Wild Stuff * The torch self igniter makes a mild whistling sound when in use. It almost sounds like a jet engine spinning up. The Bottom Line This is a great soldering torch. It gets hot fast and stays that way. It can go almost anywhere. I would recommend this item to anyone who needs an ultra portable soldering tool.
Review: Spend the extra money for this torch, it lasts forever - This torch is AWESOME. Do not be scared of the price. If you want a durable, reliable, and long lasting torch than this is the one. I have been working with fire alarm systems for 6 years now. We use portable butane torches to test heat detectors when performing building confidence testing. Many guys at my company use cheap $20 butane torches from Radio Shack. The problem with these though is that they never put out enough heat and take too long to heat up. Not only that, but they're flimsy and you end up breaking and having to replace them every couple months. A few guys however, have this torch. My boss has used his for over 10 years and it still has been going strong, after being dropped hundreds of times over the years. I know most people won't be using this torch for fire alarm testing, but it is also an excellent soldering iron. Heats instantly and it's self-igniting. No burning your fingers trying to light it like cheaper torches. You just hit a button and it goes. Don't settle for a cheap torch. If you're considering getting this one, then just do it, it will last you a lifetime.

### ⭐⭐⭐⭐⭐ easy to use, portable, versatile soldering tool
*by D***T on February 20, 2020*

straight up the best soldering tool I have ever acquired...corded are nowhere near as versatile, and now they seem dated. I used a friend's master appliance soldering tool that he has had for over 20 years and couldn't believe the work I could do soldering and heat shrinking custom wiring on one of my trucks. buy it,try it, if you dont love it you can always send it back for a refund.
