  • Right part
Perfect fit helps keep your chain run smoothly

  • Fair Price
Worked as expected

  • Is exactly as described. Worked great for fixing my son's electric Razor scooter. Is exactly as described. Worked great for fixing my son's electric Razor scooter.
I didn't know that becoming a boy mom also meant that I would have to become a scooter mechanic. My son "ran over a nerf dart" and broke this piece. This replacement fit perfectly, was easy to install, has lasted now for at least 6 months so a decent quality. It was definitely cheaper to purchase through here than it was through Razor. Altogether, I'm happy that Amazon exists for this reason. ... show more

  • Chain Adjuster
Perfect match for what I needed

  • Unusable
There was no good way to attach it to keep the chain tight. Maybe I have the wrong model, but there isn't enough info to tell you what model you need.

  • they work but noisy
Setting them up to actually work is difficult at best. Once they are on, they are too noisy as the chain rolls over the roller. That part is not a defect in the roller, it's just not something that I would use where noise is an issue

  • Works Great
It installed easily and seems good quality. It is better than the original part and reduces chain noise considerably. I am very satisfied with the purchase.
