No burrs or defects so far. Material seems solid and dimensions are as expected.

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!

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.
