I got this for the back of my Ural.  Very pleased with it,  better design and construction than the 22 liter box on my BMW that cost 3 times as much 25 years ago.  Plastic is thick and should hold up well, Latching mechanism works easily and seems substantial. Fabricated my own rack to hold the baseplate, which is also plastic but quite thick.  You have to use the key to open and close the lid, I would prefer no having to lock it every time but that's no big deal.  Cheap yellow 'Emgo'  sticker on lid covers a nasty cosmetic moulding defect, surprising on an otherwise nicely finished product.  My XXL modular lid fits in it easily, had it a couple weeks and it's so handy I use it constantly.  I may put a small cushion on the front of the trunk to make a backrest for when I have a passenger behind me.
