Review on Sisyphy Magnetic Connector Transfer Compatible Computer Accessories & Peripherals by Ted Boone

Didn't believe other reviews, use at your own risk. When used with a stock MacBook Air and charger, the cable failed after three reconnections. It was a brand new Apple cable. My guess is that the connection is momentarily shorted when it's locked. The stock USB cables are designed to connect and disconnect wires internally in the most secure way. They all connect at the same time. This product should be recalled. He goes to the trash can.
