I used the Port dble corker for 2 years and it works but I'll never go back to it! I have the Port floor corker now and if it ever breaks Ill drive 1000 miles if I have to to get a new one, oh wait a minute, I can just order it from george and have it sent to my door!
Seriously though, $3 a day aint bad but then there is gas, and wear and tear on your car and if for some reason you hit a deer on the eway there!
