Foam Cutter, Jhua Hot Wire Knife Foam Cutter Electric Styrofoam Cutting Tool, 15W Foam Board Cutter with 4 inch Cutting Machine Pen for Styrofoam Foam Cutting, Arts, Crafts DIY

I found a few reviews that said the rod broke off almost immediately. I can see how that could happen. It starts to bend greatly if you are trying to go too fast. It is a slow process but is neat and clean unlike using a knife or saw. Then I figured out if you use a sawing action (up and down) while using, it moves quicker and easier. I also turned it when it started to bend a lot in one direction. I hope this helps someone!

Love this hot wire. Went through the styrofoam like cutting through butter. Crazy hot and fast. Be careful when using, it is HOT and can easily cut off more than you wanted to. No styrofoam is safe in my house anymore, been practicing, practicing and practicing making more complex cuts.

This was my first hot knife buy and it works as it should. It's very easy to use and was inexpensive. I wish there were some kind of directions being a 1st time user.

Bought this to trim some styrofoam insulation and less than impressed. This thing does not have enough power to stay hot enough to get through a 4 foot length of material. The hot knife “blade” being a flimsy 1/16 inch metal wire bends as soon as the blade cools slightly. Ended up having to make multiple passes to get through material. Gave up and went back to drywall saw and clean up the mess after. This being the flimsiest option for foam cutter is not worth the cheapness as its basically useless. For anyone wanting to complain about the smell.. what do you expect heating up and my melting polystyrene. It’s going to smell terrible but thats not a defect of any hot knife.I should have spend a few bucks more and got the sturdier version thats better able to maintain heat. Oh well.

Used it to cut foam for my bearded dragons deco. Worked great! Cut like butter!

I had some large pieces of styrofoam to break down. This does not work for large pieces. The rod/pole is too flimsy and will bend.it would probably work on smaller pieces just fine. The pole/rod also was all sticky after just cutting through a small amount of the styrofoam. It did not make a mess (no little pieces everywhere that are terrible to get rid of).It did what I wanted just don’t buy for large pieces. I am returning.

Encantada con el producto recibido, muy práctico para el uso destinado

I didn't want to spend much so I went by the price tag and got what I paid for. This product is better than nothing, but not by much. I thought it was longer, but that was my fault for not reading closer. Just looked longer in the pictures. Not build very sturdy, bends when you use it. It also heats unevenly. Part closer to the handle gets hotter and therefore will cut quicker than the other half. Also please notice it doesn't have a on/off button. To turn it off you have to unplug it. It sparks when you plug it in. Finally it has a fairly short chord so you would need an outlet very close to where you are working. Plan on throwing in the trash and buying better brand/model.
