Let me start by saying this little plastic welder surprised me! I used it to fix a cracked bumper on my old pickup truck, and it held up even after weeks of highway driving. The repair isn't museum-quality, but for hidden areas, it's perfect.
The tool heats up crazy fast - like 2 seconds and you're ready to go. The front light is a nice touch when working in dim garage corners. I especially appreciate the comfortable rubber grip; my hands didn't cramp up during longer repair sessions.
While it worked great for my bumper and some motorcycle plastics, I will say the 50W power has limits. It struggled slightly with thicker plastic pieces. For most common car plastic repairs though? Absolutely gets the job done.
The included staples are solid quality - no rust issues here. Just remember to practice on scrap plastic first if you're new to welding. After my initial learning curve, I've used this for multiple projects beyond just cars too!
