## Customer Reviews

### ⭐⭐⭐⭐⭐ Great product
*by T***D on March 10, 2025*

Fast shipping, performed perfectly, saved my tail fixing a cracked poly tank

### ⭐⭐⭐⭐⭐ it is not easy. Using epoxy or a heat knife never gives ...
*by T***N on November 26, 2016*

This tool is a dream come true. I recently purchased a salvaged motorcycle as a project not too long ago. The plastic farings had snapped off in several places due to it being dropped on both sides. I have tried repairing plastic before, and let me tell you, it is not easy. Using epoxy or a heat knife never gives you the type of control and precision you get out of this kit. It includes a booklet with all the different types of plastics it works on. Not only that, but it also has different techniques for fixing different types of breaks. It also has recomendations for different tools and epoxies if the plastic isn't compatible with this tool. Very helpful and I learned a lot just by buying this. Saved me hours of gluing.

### ⭐⭐⭐⭐⭐ This welder is FANTASTIC!
*by R***I on April 30, 2016*

So I bought this to fix an old dash. Even just for this purpose, this welder basically paid for itself. But since then, I have had a lot of uses for it, and it works great! I bought new polypropylene fender flares for my truck and screwed up a bunch of holes. I used this unit to plug them, and you can barely tell the bad holes were even here. I then screwed up my welding helmet and used it again to fix it. It basically saved me the cost of a new helmet. I have a couple of kayaks and I know it's just a question of time before I gouge the hull or even poke a hole through it. This little welder will come in really handy!
