## Product's reviews:
- Great service! - It was all sent perfectly and on time
- Sleeve - Thanks for quick service and delivery was not long!
- Muy buen servicio y rapidez en la entrega - Primera vez q compro con esta compañía, recomiendo ampliamente comprar con ellos y claro q volveria a comprar otra vez muy buen servicio y entrega rapida
- Didn’t use yet - I really didn’t use them yet but the belts I received were actually Carlisle belts which are made by Timken. I had ordered a belt that I knew was Carlisle at the same time to try out the difference brands and it was the same belt. The only difference was the TB Woods belt was $10 more per belt so you might as well just buy the Carlisle/ Timken directly.
