My opinion: Hartzell is a very nice company with outstanding products and service. After replacing mags (Left, Right) the little ship starts very quickly and mag drops are super smooth. Definitely couldn’t be happier! The folks at Hartzell are excellent to work with. They knew exactly what I needed.

The shipping container was exceptionally strong and snugly fitted.
