make sure the arm arrangement is compatible with your bikes, I returned mine as it didn't work with the frames I had as the arms go through rather then over the bikes.
I replaced it with a thule.
Agreed – The arms can go through bikes 2 and 3. When first fitting the bikes on it takes quite a lot of time arranging them so they fit. ie which way round each bike goes, where the pedals should be, how far left or right each bike should sit, how the arms are positioned etc
I even moved the arms into a different order on the carrier frame (meant dismantling it). But once done, loading bikes is very quick.
However as forge197 double check just in case you have bikes that may prove awkward.
Cheers
