## Product's reviews:
- Excellent customer service - The couplings are just what they are supposed to be. But I wanted to comment on MRO. This was my first order with them and I was extremely surprised at how well the company is run. I will be doing more business with them in the future.
- Quality - very high quality. using these gears in a model 9 cylinder radial engine with a 1"
bore. about 8 h.p. , for oil pump a scavenge pump timing gears and distributor . very good quality gears.
- Speed reducer purchase - The purchase was easy it did take two purchase until we got the correct part I guess it was a fault on both parts as we were looking at the wrong part number, but overall the purchase was good part fit perfectly. Thanks for your support.
- Worm - Haven't used them yet, but they match the worm gear perfectly. They should serve the purpose for which I purchased them.
