I got my tool today. I haven't had a chance to try it out yet. Its the size of a credit card and about 4 cards thick. I haven't tried it out yet, but I am impressed by the design. I'm hoping I'll need some gas this weekend to try it out on. I learned last weekend how much of a pain it is to fill a tank on a GS with the nozzle's foreskin, so hopefully this will make it easier.
