Had this for about 3 months and has worked great but I'm getting ready to purchase a 2nd bike for my wife so I bought a 3 bike trailer. This is the ABT model and sells for $199. I'm also including a Reese anti-rattle locking hitch pin, which as far as I'm concerned is a necessity for using one of these style carriers if you don't want it wobbling all over the place. If you don't want the hitch pin then I'll knock $20 off the price and you can have just the carrier for $70. They work great and I've taken the bike on several 90+ minute drives without even realizing it was back there. I don't even think my gas mileage changed when I had it on.
