Electric Hot Knife Foam Cutter, Vickes Cutting Hot Pen Hot Wire Cutter 15W Electric Foam Cutting Machine Pen 10CM Styrofoam Cutter Heat Cutting Tool Kit

This product was very easy to use and very effective for the project that I did. I used it to make cartoon characters out of foam board for my kids bday party and they came out perfect and it was my very first time using this product . Great value for your money and nice size .

Have to be careful with this if you want it to last , a little cheaply made , but it was cheap so ? Got what I paid for and it's lasted for my needs of 1inch styrofoam cutting

This thing doesn't get hot enough to cut through memory foam. If you are lucky enough to get a few inches cut, it looks rough and jagged as if scissors cut it. Not worth your time or money. You're better off using a sharp bread knife, much cleaner cuts and faster.

Holy cow, I cannot begin to tell you how satisfying it is to cut through inch and a half foam with this thing….I’ve seen other reviews that say it’s somewhat cheaply made, and well that’s not entirely untrue for the money. It seems a pretty decent value, I make a lot of woodworking projects that have foam inserts and it is a beast to try and cut foam with a razor knife, so I decided to give this a try and was pleasantly surprised at how well it worked.Not only does it make cutting easier, it also makes the cut nice and clean , in other words, it doesn’t leave a ragged edge. It more or less seals it giving you a somewhat professional result.If you need to cut foam, this thing needs to be in your toolbox it’s that symbol for the price totally worth it.

It works ok for the money. When hot the blade bends easy.

I feel the knife could have gotten a little hotter had a difficult time cutting thin styrofoam and phone padding that was less than an inch

this was great for taking care of my Styrofoam. We have lots of packages with Styrofoam. Makes it so easy to get it to the trash

This pen may work on low density foam as advertised but is not suited for high density foam. At high density the pen has poor penetration and if you linger to get the cut all the way through you very well might end up with burn spots throughout the intended cut.For small decorative projects this might suit your needs, but anything beyond that...sorry, not my choice.
