Question about Thule BackSpace XT Cargobox

The box is not completely tight, in very intense rain and a driving distance of more than 500km I have wrapped delicate items with some newspaper and the load remained absolutely dry. It is important to close the box carefully and correctly.

We've made several trips for hours in the rain and the interior has always stayed dry. However, it is important to close it properly. I can only recommend this product.

We have been out with the box for hours in the pouring rain several times and it always stayed dry inside. However, it is important to close it well. I can only recommend the box.

...so I can't complain, I drove 550km in the rain with it this weekend and everything in it stayed dry. A clear buy recommendation for me.

Product is ok but not 100% waterproof.
