Lightweight and filled its function.

The advantage of this type of bike rack is obviously its weight. To stay within the limits authorized by the hitch to 4 bikes is often the only solution ....
The bicycles are fixed quite easily, being able to orient the fasteners can often find a positioning solution (not for very young children bicycles but that of my 5 year old son is mounted properly). It's still not a platform that clearly has the advantage! In addition the platform gives greater visibility and aesthetics do not talk!

The system holds up well to the coupling, the clamping system is simple and effective. I slowed still on donkey and the roundabouts.

Possible inclination of bike rack: frankly, do not count on it. On the one hand the "pins" to lift lock in the grooves (even empty it is not so easy), secondly to bring the system up to 60kg with the lift it is mission impossible or so can -be being 3.

The price is more advantageous for the platforms, but you still have to add as needed adapters female executives, the lock, the plate support which significantly reduces the price difference.

Finally, a system that works and lets you take 4 bikes on a limited hitch 75kg. Thank you to the designer!
