## Product's reviews:
- Nice sprocket - sprocket is very nice.
- Flexible coupler - Very fast and reliable shipping.
- 21 tooth 12 dp spur gear - The 21 tooth 12 DP gear I bought arrived very quickly.
It was exactly what I needed to fix my RV slide out.
I had to machine it to fit, but I knew that when I ordered it.
VERY SATISFIED!!!

Price was good and MRO ships out ASAP. Free shipping. If you need real soon have to pay for quicker shipping.
