Cumplió muy bien lo ESPERADO.

This is a slick little piece of kit for people who are into 3d printing and using metric inserts. It was much more than I was expecting, with the took coming with 380 inserts from 2-8 mm as well as 1/4-20. The tool itself is actually a temperature controlled soldering iron with a sturdy silicone sleeve over the hot pointy end. There are individual swappable tips for each size of insert. The iron is nicely sized and easy to handle, heating quickly. Just pick the size, install it on the iron, turn it on and when ready, press the insert into place.For those who are not quite comfortable placing inserts, there are of number of print-it-yourself plans available: Some of which require you to heat set inserts so you can heat set inserts. :?

This actually works very well.No instructions but kinda self expanding.Gets hot enough to put inserts in nylon/cfGreat value for the price. Will need to re order inserts soon.

Great item, easy to use

Great for uses around the house and the included kit is great. No idea why the tip continuously bends but it came with a replacement
