GOCHANGE 4 in 1 Foam Cutter Set, Electric Cutting Machine Pen Tools Kit, 100-240V / 18W Styrofoam Cutting Pen with Electronic Voltage Transformer Adaptor

I'd purchased some Expanded Polystyrene (eps) foam from Silverlake on Amazon for a craft project. Bought this tool kit so I could cut and shape it. Couldn't be happier with this purchase. The foam came with a little loose shrink wrap around it, so it was kinda smashed (I have a separate review for that, this is just words to the wise if you buy foam online). The various heads on this tool heated quickly - like within:15 seconds it was hot enough to work. There's no temperature control - it's just on or off. But that seems to be the industry standard- particularly for an inexpensive tools such as this. I've never used one of these before I can see where it can take a little getting used to. The wire head seem to make very smooth cuts whereas the metal heads sort of just melted everything and left a more textured surface. (see picture I uploaded for examples). All the heads worked well. I just need to learn a little finesse- they are hot and the EPS foam melts fast! I'm not advocating for this, but I was in a bit of a hurry so I swapped heads frequently. Once I powered off the wand it seemed to cool as quickly as it had heated. Granted, I DID NOT touch any of the metal heated bits, only the base of each head to change them out. So I was able to work pretty seamlessly by just switching unit off giving it :15 seconds to cool and swapping the heads out. Again this may not work for you... use common sense and don't burn yourself. Also, I wore a respirator while doing this in a very well ventilated area, so I don't know how much it smelled- but be mindful of those brain cells! One side note for beginners here: the thick metal heads melted EPS so quickly that I ended up sort of caramelizing or burning a few spots. Not a big deal I could kind of scrape them off and they were just a light brownish color. The tool seems well made and sturdy enough. I don't plan on using this often, so anticipate it should last a good long time. Overall, this was a fantastic purchase that works very well 👍

Heats up fast and cuts through foam cleanly without melting mess or drag. The different tips make it easy to handle precise carving and shaping jobs. Perfect for props, crafts, and model work — great value for the price!

We ordered this for a project we were working on where we had to cut several pieces of industrial foam. It works great and we have no complaints. It does get quite hot so make sure that you are using safety gloves and keep this away from children and pets. But it does a great job getting very straight lines in the foam.

Why isn't this a 5 star review? Well, when they designed the power cable for this set, they decided that you wanted to be right up against a wall socket while you're working. WHY would you put a 3' power cable on a crafting tool like this? That is the kind of thing that just makes me mad. After I hooked this onto an extension cord, I was back to being happy. The unit is light weight and easy to work with. The heads are simple to change out while seating firmly in place when in use. All of the heads heat up fast and cut through even dense foam without any fuss. For the Halloween decorations, I'm using 3" high density moisture insulating foam, and this heat knife has made a huge difference (not to mention that I'm not making foam "snow" with a saw or knife). Great value and, thus far, great performance. I definitely recommend. Picture of homemade and store bought to show a mix

If you need to cut or shape foam these are fantastic. I used them to shape and cut styrofoam for a train layout. Well worth the money.
