I had this rack for a while. Its a very nice rack but there are some things you should know.
1 - The rack is HEAVY. If you plan to take it off and on the vehicle, you'll get tired of lugging it around quickly.
2 - Apparently Thule has changed the hitch pin design some and the new racks arent as stable as the old racks, which is a shame. The one I had, you could jump up and down on and it wouldnt budge in any direction.
3 - The front wheel mechanism has to sit against the brake caliper so you'll end up having to recenter the caliper every time you transport the bike. No big deal but a PITA.
4 - Depending on the vehicle you put this rack on, you may have to cut down the wheel trays to get the rack to fold up.
Personally, I would take a look at the Saris CycleOn. It's lighter, holds the bikes better but isn't quite as sturdy from a "Im going to jump up and down on you" standpoint.. from a bike transporting standpoint, its more than adequate.
