## Product's reviews:
- 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.
- Boston gear order - MRO had the items that I needed. I ordered them and they were shipped faster than I expected. It was a pleasant experience all around.
- 12d.p. 14t spur gear - This item was closer to exactly what I needed than I had thought possible to find in the last 75 or so years. quite affordable, too. I almost didn't look, but when I did, there it was. I had in hand in just a couple of days.
- 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.
