RONGTER 4 in 1 Hot Wire Electric Foam Cutter Kit, Styrofoam Cutting Tool 15W/ 6V with Case, Heated Foam Carving Knife Kit (Toolbox White)

Works great. I used this to cut some thick insulation foam for my garage door. This is the third time I’ve done this project and I REALLY wish I’d bought this kit before the first time. It was so easy to use and made the cuts like a hot knife through butter. I was able to use the mount and some scrap wood to create a surface that let me make repeatable, flat smoot cuts over and over. Really looking forward to using this for my next project.

Was it fast? No. Did it work well? YES! This thing is fantastic at cutting foam. I used it primarily on the harder 2" pink rigid foam. Most of the time I had 2 pieces adhered to each other (spray adhesive foam works best) and it cut like butter. It's juuuuust 4" long, so it was hard to get to the end of the 2nd layer of foam but it just made it. I had to go slow, but it worked like a charm. I read some people were breaking the head off which is ridiculous. You would have to push amazingly hard in order for that to happen. It will start to bend if you are pushing too hard, so realize that and back off a tad. Just take your time and let the knife do the work! I used it to make big size Monopoly pieces for Halloween at work, and they turned out great. Cutting stuff in 3D is quite the adventure! :)

The cutter worked well and was easy to use. The only downside is that there are only 7 wires, and each only lasted a few minutes before either breaking, or slipping out of the ends where they were crimped. However the description does say “styrofoam cutter” and I was using it for EVA foam which is denser and harder to cut through which could’ve been part of the problem. Overall, seems well designed and worked as intended though.

Outstanding Tool. Works great on foam and plastic.

Heats up fast and easy to use.

BEWARE - stopped working after about 6 months. It's a great "intro to the hobby" hot wire cutter. Worked great at the start, comes with multiple attachments, just doesn't last. Attachments and power cord plug are delicate. It turns on, then off immediately. Wiggle the attachment / plug and it turns on / off, won't stay on. Frustrating. Messaged the company, who said the warranty is only 1 month. Again - it works, but only for 6 months. Good introductory product.

Not hot enough. Trouble cutting the foam. Have to cut a little, wait, cut a little, wait...

Got this for my husband he makes pieces for my Christmas village out of styrofoam. It comes with a handy case and different tools for different types of jobs. Not a great picture but this done with the cutter.

This is the best product on this price range on Amazon, I have tested 2 others that they had issues and I decided to spend 20$ more and I don’t regret it. Smooth and sturdy!
