Excellent.
If you tighten it well on the towbar, it doesn't move at all.
It's good to have an extra strap to tighten the front tires so they don't go back and forth, but even with the straps it comes with, it does the job.
You can tilt it so that the trunk opens for SUVs and five-door cars that open from the bottom. Of course, it takes a lot of strength with the bikes on top, but usually you will open the trunk after you have taken the bikes down.
I wouldn't change it for anything at this price and even less since I got it.
Of course, Thule has much more expensive ones with lights and such, but I considered it excessive.

In the first installation I made, it doesn't show particularly sturdy construction. I haven't used it yet, but I would say it is quite expensive compared to the quality it offers, and I even bought it 30 euros cheaper than the offer in the store. I hope it will perform better in practice
