## Product's reviews:
- 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!
- Office manager - I got exactly what i ordered. Works like its suppose to..
- Fast - good price, fast delivery, search works very poorly
- 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!
