## Product's reviews:
- Fast shipping - I ordered this part hoping it would arrive within 2 weeks because I had an emergency situation with an employee waiting to repair a piece of equipment at a customer’s location. The part actually arrived halfway across the country in 5 days including the weekend. MRO processed, packaged and shipped it with incredible speed. Thanks again!
- Needle gear - I'm very happy with my purchase. I found exactly what I was looking for and I received it in a couple days. I will recommend your company to others and I hope I can deal with you again. Thank you!
- New lead screw gear. - Used this gear on a new lead screw l made for my old 1919 LeBlond belt drive lathe. It worked great for my application.
- 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.
