It does what it is supposed to do
I use it with a Cannondale Mixte on a Hollywood Rack. Have taken a couple long (800 mile) trips with no issues.My only concern with this type of design is that the bike is essentially hanging by the handlebars and the bicycle seat. Make sure your seat and shaft is tight - you don't want it to pop off if you hit a big bump. This has not been an issue for me, but I worry about it.
