## Customer Reviews

### ⭐⭐⭐⭐⭐ Does the job great.
*by R***R on April 6, 2025*

Performs exactly as intended, easy install, minimal appearance on bike due to small size.

### ⭐ Broke within 1 month of use
*by S***L on December 12, 2024*

One of the tensioners snapped within 1 month of use. Wish I had bought something more heavy duty instead. I had only rode my bike on simple flat roads (no trails / tricks).

### ⭐⭐⭐⭐ Not for BMX big stud
*by B***N on July 9, 2024*

For youth, the smaller stud, not the 14 mm/ Big stud
