Never used it. Most racks are similar in design. It is all about the quality of the arms and straps. I wouldnt trust my bikes on it though...I would probably hesitate to put 3 bikes on there especially if you have heavy bikes.. Just dont go drifting around corners...and just be aware that you are carrying loose weight on there. A cheap bike weighs 30-40 lbs.

Also, adjusting the straps securely makes a huge difference...spend a good amount of time making sure they are adjusted right. And I also like to do some dips on the rack before putting my bikes on there. And yes, the Saris Bones can be used to do dips from my 145lb ass
