Review on 🔧 Lisle 21700 Wrinkle Band Ring Compressor for Smooth Compressions by Jessie Ritchie

Cans don't work well because the buckle that pulls the band down only pulls down the middle of the harmonica band and the edges "flap" or "bend" causing the piston ring to break can avoid tightening effect. I ruined 2 piston rings with it. This product may work well on older full rimmed pistons, but the more modern, lower profile vk56de engine pistons did not work for me. A MUCH better choice is the hopper type ring compressor.
