## Customer Reviews

### ⭐⭐⭐⭐⭐ Easy to use
*by M***D on July 28, 2025*

Great product. Works as intended. Easy to heat with a soldering iron. No special tip required, just a large cone tip.

### ⭐⭐⭐⭐⭐ This is the only brand to buy, consistently perfect. Never fail.
*by T***R on August 15, 2025*

Buy these, no matter what.You’ll regret buying from others, promise.I use thousands of these for my products for customers. They are essential to my business. I recently tried to buy another brand that was a little cheaper and it was a bad mistake. About half of them have damaged or defected threads, but you don’t know until after you try a screw in them. This has caused me many failed prints, a lot of money wasted. All because I tried to save a few bucks. I will never go to any other brand, this is literally the only one I trust.I don’t leave reviews, but after the nightmare with the other brand that starts with a U, I felt it was imperative I help out others.Don’t buy anything else.

### ⭐⭐⭐⭐⭐ well made, very useful for 3D printed replacement knobs
*by F***O on July 30, 2025*

These work really well in 3D-printed knobs for photography equipment (light stands, etc.). I also used them to 3D-print a broken knob on an old steelcase keyboard tray I like.
