## Product's reviews:
- Masterdrive f 1 3/4" inner qd hub - Used maybe a dozen of these, zero problems. Why pay 50% more for a name brand when these work great?
- Masterdrive - I'VE USED LOTS OF MASTER DRIVE PRODUCTS AND ALL OF THEM HAVE BEEN EXCELLENT QUALITY.
- Quality product - Heavy duty. Not likely to bend or warp
- Just what i needed - I needed a very small belt for my rock polisher, and it was just the right size.
