Review on Caliper TUTOOLS Piston Spreader Ratchet by Matt Abba

Looks like this would be a great caliper tool but I ordered one and the ball bearing in the derailleur fell out when I took it out of the box! Didn't even get around to using it. So sent back and got another one but he did the same thing when he flipped the switch back and forth the bearing fell out again! Don't order this tool, cheap switch will make it useless.
