## Customer Reviews

### ⭐⭐⭐⭐⭐ Good value
*by L***I on December 10, 2025*

Awesome inserts, work very well in 3D prints

### ⭐⭐⭐⭐⭐ quality product
*by S***Y on February 8, 2026*

I use it in my 3D projects. It's a successful product. I haven't had any problems.

### ⭐⭐⭐⭐⭐ Great inserts at a great price
*by J***R on December 14, 2025*

A friend said he finds metric size bolts to be cheaper than the Imperial sizes. He is definitely right. I am shifting some of my 1/4 inch sizing to M6 but there are times you need the added strength that 1/4 bolts provide. That being said, I have both 1/4 inch and M6 bolts/machine screws so I am happy to have these inserts as well.
