## Product's reviews:
- Great price on gates belt - Great price and fairly quick shipping.
- Gates 89020710 5m710 polyflex belts - Best deal on these belts.
- Fast delivery - Thanks for fast delivery, good price and service.
- Gt4 cog belt - I've not had a chance to try it out but if it's at least as good as the 150 hours I had on the GT2 belt when I decided to replace it, I'll be a happy camper!
