## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great for 3d printed parts
*by A***S on December 14, 2024*

I've used quite a few of these and I will say I've had zero issues with them. They insert fine with a soldering iron and the threads are accurate and clean. I have zero complaints or suggestions for improvements.

### ⭐⭐⭐⭐⭐ works as intended
*by B***K on July 22, 2023*

works how they should. holds solid

### ⭐⭐⭐⭐ Sampling assortment
*by P***T on April 15, 2023*

These work really well in my 3D prints. I print in ABS and PC a lot at work and these work like a charm. I am a bit disappointed in the fact that it is more a sampling assortment than a utility assortment. By this i mean there are a ton of sizes but not many of each so its good for trying something out but you'll need to purchase a refill of anything you like. For example, there are 4 different sizes of m3 inserts but only 15 pieces of each. Vigrue loses a star though for bagging these two un-marked bags per compartment in their little organizer. Might not seem like a big deal, but i still have no idea how to tell which bag in the 1st compartment is m2x2x3.2 versus m2x3x32...
