Review on Adjustable Tapered Piston Ring Compressor - Checkered Flag Performance, 3.940" to 4.060" by Edris Holwell

It seems to be a great tool but the description is wrong in some places. Declared in places as 3.09"-4.05" and 3.9"-4.05". I don't have piston jugs so this doesn't work for my application. In hindsight the correct male height of 3.9-4.05 inches is much more reasonable, it can't go down to 3.09 inches as that would only compress the ovals and that's a terrible idea. Please correct your descriptions to match the correct title size!
