Easy, fast, secure
I literally changed out the bike mount from my old one to this one in 15 minutes and the bike goes on in seconds. Close the clamp, lock it, strap the rear tire and your off. I've seen reviews that this model has a design flaw, but I haven't had any issues. My box was marked as Jul '08 date of manufacture and I purchased in July, so just be sure you get a new one.
