I have used this type and it works well, I did have an issue with one that the automatic fuse reset did not work, however I have sent it back for repair at their request. I am very happy with this product.

It was shipped very fast and I would recommend them to everyone. My son loves it!

Just what I needed to further my Mountain Scenery work. Was able to cut down foam slab edges much faster than using my foam rasp tool.

Then I followed up with the rasp to blend the edges to a smooth slope.

I also narrowed the arms to make a sharper wire loop to carve out a ditch and pond into the flat foam base layer.

Great tool

The kit was easy to use, just plug-n-go, works very well & leaves little mess. It made sculpting foam a breeze
