We got one a while back…pretty happy with it.
Best bit is after removing the bikes, the wheel holders and rear lights slide in, then you can lift it off the towball and plonk it straight into the boot.
This is a good thing, as the rack itself is a fairly weighty bit of kit and its a bit awkward to carry anywhere. Had ours about 3 months and its only come out of the boot a handful of times when we’ve needed the space.
Also I’ve not really worked out a way of storing it without it being at risk of falling over or scraping all the paint off it, if we didn’t keep it in the car I think I’d put a big hook in the garage to hang it from.
As you can stick it in the boot it avoids any issues in tight car parks with it getting in the way, or other cars pranging it if its out of their view when parking. We normally put it in the boot whilst riding.
