## Product's reviews:
- Belt 5vx940 - Excellent Speedy Service. TLC Will continue doing business with MRO.
- 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!
- Gates b-55 belt - We use these belts on wastewater lagoon aerators which run 24/7. Great price for a high quality belt and receive them within a few days of ordering!
- Gates 89020710 5m710 polyflex belts - Best deal on these belts.
