Review: Good qaulity, nice selection, fair price. - I appreciate the nice selection of sizes and overall quality of these inserts. They work fine for my applications. Install easily using the Kadrick soldering iron tips. Since my application tends to be "one and done" use where the screw is seldom, if ever, removed, I can't comment on durability. I don't see any red flags that make me think these are less durable than any others that I have used. If I have one negative comment, it is that I would like the assortment to include more sizes of M4 and perhaps fewer M3. That said, this provides plenty of selection for prototyping parts and validating design and functionality. If I find that a different length insert in the prototyping stage, that is easy to resolve when I purchase larger quantities for production runs.
Review: Very good collection - well made. - Great for my hobby level 3D printed parts. Excellent assortment, all seem very well made and are highly functional. They fit my heat set kit well and I have found none that seem mal formed so far. Will buy again.
