Great for my hobby level 3D printed parts. Excellent assortment, all seem very well made and are highly functional. They fit my heat set kit well and I have found none that seem mal formed so far. Will buy again.

Great product and easy to use.
Really easy to use and makes it very simple to add a threaded hole in plastic. I used it to add a radio to a pelican case using a regular soldering iron.
