Worked great!
I needed a hot knife to help make ports in a project enclosure. I bought a much less expensive one before the Huanyu that did not do the job; there was poor contact between the blade the heater so the blade didn't heat up efficiently. The Huanyu has several set screws that lock the knife tools solidly in place - they heat up to correct temperatures and cut the plastic project box easily. This was quite a bit more expensive but it got the job done. Very satisfied.

It works... it's good...but it's pricey.
I can't believe this thing costs so much, but it works and I haven't had any issues with it. Seems to be a quality tool. Hard to find good quality tools without paying an arm and leg. And even when you do there's time's when the quality is questionable. You definitely get what you pay for in this case. This is a good quality tool.

High heat, accurate cut
Husband used these as a fabricator for office panels. He wanted one for personal use & has been searching for a while. This product is exactly what he was looking for. The gun heats up quickly, is easy to use, provide an accurate cut & cools down almost just as quick.

Heats quickly
Glad I got this one instead of the lower wattage ones also offered on Amazon. It heats up quickly and cuts nicely. I like that it is activated by a trigger and not just a hot iron. Good purchase.

Works Great
Just used this on garden fabric, it works fantastic. Just don't get in a big hurry so that the plastic fuses so it don't unravel....

Extremely dangerous to novices
The cutting blades can be powered up red hot in just seconds. I used them to melt a car fender split back together and cut the top off a rain barrel.

Quality Tool
Great quality and served my needs for my projects. I don't know what these go for normally but it seemed like a good price for what you get. Solid construction and all pieces feel high quality. Hoping this lasts for years to come.

Envío rápido y excelente producto
Funcional solo que al trabajarlo en medianas jornadas se llega a calentar todo el aparato ocupando guante para temperatura ya que no es tolerable trabajarlo al tacto. Otra es que la navaja se enfría con cortes largos esto es obvio pero hace que tengas que subir la temperatura para eliminar esta deficiencia por lo cual se calienta todo el aparato. Esperemos ver cuánto tiempo trabaja.

works awesome for landscape ground cloth
I bought this hot knife to make many cuts in the landscape cloth for my 140 x 30 ft greenhouse that grows hot peppers. it cuts and fuses the edges beautifully with d shaped fabric knife and fabric stabilising foot on the high setting. be sure not to rush the longer cut or it won't fuse in some spots and you could get fraying.. i love this because using scissors leaves loose ends that will continually fray when moved or if there is a breeze through the place, creating horrible trip hazards. looking forward to buying the attachment to use while routering out a hollow in foam pads for under our hydroponic tomatoes.

As Promised
It does exactly as it says it will… my only wish is that it came with a manual.. other than that it’s awesome. use safely though!
