Product fit soldering gun without problem, worth the money, works well just check temperature of your solder gun, it will heat up fast.

I can't believe this kit works so well and is so cheap. I'm lov'in it.

Excellent product they fit correct to my solder iron and do there job perfectly ! definitely recommend

Works perfectly fine for installing threaded inserts into 3D-printed projects. Docking a star because the sizes aren’t indicated or engraved anywhere on the tips themselves.

I think these are better than the screw on type. They heat up fast and feel solid and stable compared to others I have used. So far, no funny odor or discoloration when used at higher temps.

These work great for various brands of inserts and fit my soldering iron well.

Works great with X-Tronic 3020! Nice little case, 10/10

Haven't gotten a chance to use it yet but I'm impressed with the packaging and organization. Should fit for what I need and allow for better quality of builds. The different tips allow for multiple functionality, it's a great value for money spent.

Werkzeug passt nicht für M6 Einsätze, Rest in Ordnung.
