## Product's reviews:
- Great price on gates belt - Great price and fairly quick shipping.
- Gates 89020710 5m710 polyflex belts - Best deal on these belts.
- Thank you! - First time customer and I will return! I will tell all of our associates what excellent service we received! You saved us from an ugly situation. With a hefty order needing to go out and the belt broke on our Seiki mill. I called on Friday. I wasn't even expecting shipment until the following Monday or Tuesday but we received our belt the very next day!!
The price was fantastic, not to mention FREE shipping!!! I want to thank everyone from the sales agent to the packing and shipping department.
Seriously....this was the best service we've received in ages!
