## Product's reviews:
- 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!
- Blower belt - Like MRO...quick ship/good price but my F2 supercharger makes short work of these belts.
- Mechanic - Cut the bell when you said I would get a chance to install it seems to fit I still need to test drive
- 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!
