It works but one bolt already broke and I had to replace it. It is working again. However, the gear at the top of the part seems to be made of soft metal so I am not sure how long this will last.
Excellent and fast service
The product gave us good quality service.
Bought as a gift. Person has several wash tubs full of black walnuts and butternuts. Sits in garage cracking for hours, gets large pieces, adjustable, durable for sure.
