Good quality inserts. Clean threads, consistent diameters, great selection of usefull sizes, and I really like the tapered end for starting them in the holes straight. Haven't had a single problem with them. Will definitely buy again. I recommend printing the holes to be a snug fit on the tapered tip and a small chamfer helps eliminate the squeeze out when they melt into the part.

I bought these for a 3d printing project I was doing, and have ended up using them for a few other projects as well. They're surprisingly easy to press into an object, and they hold well. I haven't had any issues with them getting pulled out. I also bought some tips for my soldering iron that fit these inserts, and that likely helped the process. These are great!

Great little assortment. The packaging is great too. Mine were wrapped up tight and no loose pieces.

I only needed M3 at the size this provided but at least I may be able to use some of the other sizes for other projects. I think McMaster could still be more ideal for these kinds of things but if you don't want a bag of 100 and only need a couple hand fulls this gets the job done.
