Review on 🔧 Lisle 21700 Wrinkle Band Ring Compressor for Smooth Compressions by John Mejia

These things used to be fine, but in this latest Taiwanese version, the grooves are punched the wrong way, causing sharp burrs to scratch your nice new piston and rings. You either have to spend a lot of time filing and sanding the burrs smooth, or take out the rivets and take the damn thing apart, flip the slotted tape and bend it again and hope for the best. All in all a waste of money.
