Review: Works like how it says on the tin. - These little guys worked a treat! I have never used heat set inserts before, but they worked perfectly. I used them to assemble a 3d printed test bench for computer components. Excellent items.
Review: Good inserts - Work great on PETG prints. I don't use a soldering iron to install, instead I insert a bolt through the hole, screw on the insert, heat it with a small torch and pull it into place. This ensures the centerline of the insert lines up with the hold.

### ⭐⭐⭐⭐⭐ High quality and seat very well in plastic model
*by J***R on December 14, 2025*

Really good product. I wanted a shallow insert so there would be room in whatever future models I make. Certainly, if I have room for a longer insert, I would use it instead.
