You have to buy this tool if you own the stainless steel media and rotary tumbler. The magnet picks up the pins and drops them with a pull of the handle. The magnet is designed so that it can be operated with one hand. The device fits into the opening at the end of the drum. One pull and the pins are dropped. It so also very good for picking up stray "escapee" pins as they will wind up all over the place. The design is genius.
Pros: Makes picking up the stainless steel pins and dropping them in the tumbler easy
Cons: None
