Only when I was mounting it I realised it is one side box, so can not be open from both sides. This might be a bit inconvenient. Mounting it is a bit time consuming, but to have the convenient mounts it would be more expensive.
It holds well, it is quiet when driving and holds a lot. I was able to put there 2 pairs of skis for adults, 2 for kids, 3 helmets, ski boots, 2 pairs for adults, 2 pairs for kids, ski clothes.
