I bought it for €130. It is very quiet and the installation was quite easy (within 10-15 minutes, even though I generally don't even know how to use a screwdriver).

It is not aluminum as stated in the product name, but plastic. However, I saw it up close before I bought it, so I was aware.

There is a button where the passenger's backrest touches, which activates the light on the red "X" on the back of the top case, which has 3 modes (steady and 2 flashing).

Finally, by unlocking the lower lock and pulling the top case slightly outward, the box is removed quite easily. I only use it for trips, so I generally remove it.

Excellent luggage carrier with a metal base. Safety fasteners and internal lining. Everything is OK... but the red light X is ultimately a bit lighter, it has a pinkish hue! Nevertheless, 5 stars because it is also a quieter luggage carrier under 160 euros! It fit very easily onto the SHAD base. I recommend it!

Very sturdy construction with specifications always in line with its price. Silent as long as it is installed correctly and balanced with a level. The LED light operates with 2 AA batteries and has 3 operating modes. It fits a large helmet with spoilers, etc. The internal lining is very good and comes off easily. The downside is that it does not have a support wire rope that holds the opening door as well as the two plastic hinges which could have been metal.
