## Customer Reviews

### ⭐⭐⭐⭐⭐ The Solution for Strong and Durable Threads in 3D Printing
*by A***. on September 14, 2023*

The kit comes with a variety of sizes to fit different holes and the brass material provides strong and long-lasting threads. I highly recommend this kit to anyone looking to add durable threads to their 3D prints.

### ⭐⭐⭐⭐⭐ Use a soldering iron
*by C***D on January 29, 2022*

The best way I have found to install these is with a soldering iron. If you are installing these in a blind hole you might have to cut the tip down to install them. These worked great for me but I have only used them in pla and I imagine they would work just as well in petgnor abs.

### ⭐⭐⭐⭐ They are What They Are
*by P***P on January 15, 2021*

A little hard to orient these perfectly vertically even with a press. But they are very cheap and it is possible. I have found these useful in early non-load-bearing 3D printed prototypes where I don’t want to throw down the 30cents or more per fitting of better quality inserts.A slight chamfer to the exterior of one side would make these infinitely easier to seat properly. Other brands I can get to seat straight by hand with just an old soldering iron.
