Customer Reviews
I am updating from last review. I just got the belts in after a month of waiting.
Belts fit tight around the drum. Good and bad. I have to pull the wheels off every time I need to change belts. They don’t slip.
Customer service was average. Didn’t feel like they cared to much about my shipment.
Belts do polish well.
Placed my order 2 weeks ago and still has not made it to me. I have no idea how well they work. Will update when/ if I receive them.
Slow on shipping but finally received
