Review on Caliper TUTOOLS Piston Spreader Ratchet by Sivabala Mickel

Defective immediately. The key turns, but nothing happens. Not a complicated tool, so let it get the job done. I did not test this tool before jacking up the car and removing the wheels and old brake pads. Everything is ready to compress the cylinder with this new tool but it never worked. Had to reinstall everything that was taken apart to go to the hardware store to get a c clip to complete the install. A few hours lost. Why me?
