## Customer Reviews

### ⭐⭐⭐⭐⭐ I ended up reselling this
*by C***S on November 17, 2021*

Tried on three different occasions to get this to work belt slipped right off there was no lip to hold the belt in place. Looked up other manufacturer designs and they weren't like this they have lips on them. So I figured this product would just put it lips on me.

### ⭐ Junk
*by R***T on December 30, 2022*

Idler pully has wrong bearings on it. If you tighten pully against bracket, pully does not turn. The pully MUST be tight, otherwise the belt skips.

### ⭐⭐⭐ It works great no pop from chain
*by B***  on August 19, 2019*

I like the product , I only wish it came with a little instruction and or a sprocket hub adapter . Since I received the belt and put on ,my bike has been down ! 😓 when I parked it because of broke chain and ordered belt drive because I was tired of hassle with chain , the clutch drive pulley is rather large and tight fit but works ,I can’t wait to get it all good again 😓 . The customer service for this outdoor power equipment was absolutely outstanding! Awesome !
