## Product's reviews:
- Exactly what i needed - Item was exactly what I needed and a perfect fit for my project. Extremely happy.
- 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.
- Worm - Haven't used them yet, but they match the worm gear perfectly. They should serve the purpose for which I purchased them.
- 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.
