I have had this box for 3 years now and it does the job. Holds up against everyday use, rarely do I take it off. Has made multiple trips across the country and still looks great. It will hold numerous pairs of skis, think the most I have ever had in there at once is 4 skis (100+) underfoot, but that was some extreme packing. I have put up to six skis in there when the east coasters are tagging along 110 or less underfoot. I guess my only complaint would be that the lock can be pretty stiff if it is cold out.
Recently had to change the locks on the box and it was no big deal, just follow the simple little guide that they come with and you are good to go. The mounts have a lot of room for adjustment so it does fit a bunch of different set-ups. I have put it on some other vehicles and its a quick install. Just need to line it up and screw it down. Definitely would recommend to a friend.
