Not a cheap option, but in my opinion, apart from 1 fault, it's perfect.
Starting with mounting it. You put the mount on the tow bar (hitch) and then press a lever down to lock it in place. The tension is adjustable and when it's locked, it doesn't move. You can also lock the lever so theives can't just lift it off. Then attach the electrics and you are ready. Mine came with the 13 pin plug (my mistake), but a 7 pin to 13 pin was available from Amazon - so no issues there.
When not mounted, it folds away and is easy to carry.
Bikes go on and the tyre slot is wide enough for the tyres we have. The main thing that holds the bikes in place are two bars which come out from the front and attach to the downtubes. It all works very well and is extremely secure. These bars can also be locked so they can't be undone. There's a couple of straps to hold down the wheels - and that's all you need. Of course, having just had two stolen, I also add a load more security - but it's not needed of you are not leaving the bikes alone.
Now, the one fault. With my EST-520's, I have to take the batteries off to get the cetral bars to lock in place. Which means the electric contacts are exposed to the elements. I'm working on making some sort of cover for them (Decathlon don't do one). At the moment, I just put tape across. The picture below shows what I mean.
Would I recommend it? Yes, undoubtedly. I had a cheaper one before it it took forever to get the bikes on and locked down.
