Great inserts. Smooth threads.
M4 seems to be my go to size when I'm using threaded inserts. This pack was a great replacement for the lack of M4s on my workbench. I used them to finish a recent project of attaching a foot to a base for my leg lamp. It worked wonderfully and the price per piece was a nice value. Easy to install and very smooth threads.

Great assortment in one kit
Bought these for some 3d prints I made and they worked beautifully. Be sure to buy the heated inserter though, as well as the various sized tips for it. This make installation almost foolproof. Great quality and a good quantity in this kit.

Awesome inserts
The sizing is accurate, all are machined properly, and they go in and more importantly stay in. Threading is smooth and the small lip at the bottom does a great job at holding it in place when setting them. Will definitely buy these again when I need more.

Seems good enough
I haven't used any yet, so I'm not sure as what to expect. Good amount of different sizes which was what I was looking for anyway.
