## Customer Reviews

### ⭐⭐⭐⭐⭐ Good Item
*by J***5 on December 12, 2024*

Right spring strength, right length. All good

### ⭐⭐⭐⭐⭐ Does it expand and then recoil for my project.
*by R***S on November 12, 2023*

I needed the springs to stretch and retract without losing their recoil and they performed excellent. The wire diameter of .046 held up well for my application.

### ⭐⭐⭐⭐ Perfect replacement for my bird feeder.
