Decent quality
Very good product, I get through a fair few of these in my 3d prints, these are as good as any others, they set in well and stay in well, the threads are nice and clean and accept the m3 bolts easily.

Good quality inserts
I've found myself buying this brand in particular. They are good quality. I have bought large quantities from CNC Kitchen, but sometimes I've needed sizes I didn't have, in a hurry, so I end up in here - choose these every time. I don't put them in hot as I don't personally think that's a good idea. I fit mine using a toggle press and add they go in, you can see them rotating and effectively cutting themselves into the material. A royal pita to get out of something is wrong, so I know they work!

Functional
Work well enough, does what they say it does well.

Surprisingly effective
A little bit of practice is useful to start with, making different-sized holes to see what works best for you, and to get a good temperature and technique for inserting. After that, these are very effective at holding screws to join printed parts together.

Ottimi solo per stampe 3D a filo. Non a resina
Ottimo prodotto. Tuttavia non funzionano nelle stampe 3D in resina. Ottimi nelle stampe a filo! Facili e rapidi da impiegare.

Top Ergänzung für 3D-Drucker und CNC-Projekte – sehr zuverlässig
Die Gewindeeinsätze sind eine super Ergänzung für alle, die viel mit 3D-Druck oder Kunststoffteilen arbeiten. Die Messing-Einsätze lassen sich sehr sauber einsetzen und bilden stabile, langlebige Gewinde, die auch häufiges Ein- und Ausschrauben ohne Probleme mitmachen. Die Qualität der Messing-Gewindehülsen ist wirklich gut – sie sitzen fest, drehen sich nicht mit und halten perfekt in PLA, ABS oder anderen thermoplastischen Materialien. Die Lieferung im 50er-Pack ist ideal, wenn man oft Ersatzteile, Prototypen oder funktionale Komponenten herstellt. 👍 Vorteile: • Einfaches Einpressen / Einschmelzen • Saubere Gewinde mit guter Festigkeit • Viel Zubehör für wiederholte Nutzung • Gute Preis-Leistung Ein super Produkt für Hobby-Bastler und professionelle Nutzer gleichermaßen. Klare Empfehlung!

Reliable, consistently sized, and fairly priced inserts
There are multiple options to choose from for heat inserts, which are indispensable for anyone who's serious about 3D printing. The quality varies tremendously, so does the price. However, this set checks all the boxes. I waited a bit with the review to test more than 1-2 of them and wow... these are definitely landing on my favorite list! After using over a dozen of them I can confidently say these are great. The thread quality is very good, the dimensional accuracy on the outside is within 0.05mm tolerance, and the brass has no sharp edges on it. They may not be the cheapest set, but the QUALITY is DEFINITELY worth the premium. In addition to being good quality, the ostensibly small touch of including the dimensions and a BIG picture on the packaging makes it extremely easy to identify them in a shop. I no longer need to make a custom label.... these are small things that make using the product way easier. This is my first set of the heat-set inserts from Hanglife, but for sure not the last one!
