Review on High-Quality Screw Caps for Replacement Gas Can: Perfect Fit for Gott, Rubbermaid, Briggs & Stratton, Kolpin, and Rotopax Fuel Containers by Russ Charmin

First, they will NOT fit older 2-1/2 gallon chainsaw gas cylinders that have a separate smaller oil tank. I'm not giving that 1 star because they don't fit in my gas tank. I give them 1 star because the strap is integrated into the cap and makes it impossible to rotate the cap when the cord is attached. The cap cannot rotate, part of the lanyard needs to be cut off completely. Very stupid design and overpriced.
