    • A great set perfect for anyone 3D printing
I had been putting off buying the Heat inserts for a long time. This was a great Buy considering it came with the iron the adapters and all of the heat inserts. Making it very functional for different projects. Not sure I would use the two or three smallest sizes but they were there with the kit. Appears to be quality product, plenty of different size inserts. And I was pleased with the price ... show more

    • Give it 4.5 stars. Just 2 small issues (read on...)
The kit is great! Good variety. The heating element heats up very quickly. The temperature adjustment is great since I have PLA, PETG, and ASA to deal with. I under-sized my first holes (but had 4 wall loops). The inserts still pressed in with just a little bit of excess PLA squirting out the top. The two - very minor - issues I found were: 1) the brass heat transfer piece rotates very easily. You remove the heating element cover and put this piece over the heating element. It's loose around the heating element, and rotates very easily, but still heats extremely quick. 2) There is nothing on the label, or any documentation, on what sizes the holes should be. I used calipers and just guessed. All-in-all, I'm happy with this purchase. ... show more

    • Works Great
This set up works great. The soldering iron heats up quickly and has a temperature dial. Set some inserts into a 3D print and have had no problems.

    • Heating iron makes easy work of melting the inserts into PLA and PETG.
