Review on Stant Flex Fuel Regular Locking Fuel Cap in Vibrant Yellow - Secure Your Vehicle's Fuel System by Brian Rivenbark

Great cap until you try to open it. It wouldn't unlock and wouldn't let me take it off. I asked the mechanic to remove it but to no avail. I finally got it, but not before I ran out of gas. I used bolt cutters to remove the top of the lock. This is without a doubt the worst thing I've ever bought from Revain. I did not ask for a replacement or refund as I almost threw the item over the lake. Only buy this item if you intend to use it for something other than a gas cap.
