Engineered and made well
Used this to install pistons on a Honda F23A1 engine, after I found out the ring compressor I had wouldn't work. I first tried a 3D printed product, that ended with a broken ring. When I got this compressor I realized how it was engineered so it wouldn't allow the rings to expand outside of the land once the piston was inserted.
