UPDATE 2024-01-11I just updated from 4 to 5 stars. This box has been absolutely awesome and the little latch flaw I cited earlier really is a non-issue. I just don't even notice it any more. I recently ran a solo 3-day motocamping trip in a nearby National Forest. I had my electronics, my loose sleeping bag for padding the electronics, and some other miscellaneous odds and ends in the box. I put my non-destructables like tent, clothes, etc in my soft luggage (Mosko gear on Motortek racks, all outstanding). I dumped the bike twice on loose rocks - slow, not incredibly hard falls, but falls none the less. The Lesanm box held up just fine (never actually touched the ground in the falls). The mounting plate was still fine, the hinges, everything. When I got home I water tested the box again to be sure and it passed with flying colors. I love this box. You absolutely *do not* need to spend $1000 to get a quality top box.I bought the 65L with just a little trepidation. I was worried it might look enormous and 'out-of-place' on my moto (2023 890 Adventure S). I thought people on the street would point and laugh, neighbors would throw cabbages from behind the bushes as I rode past, mothers would cover their children's eyes to protect them from the spectacle, it would be so unsightly it would "aggro every bears in a 40 foot radius" ... OK, maybe not that first one.So, it *does* look just a little weird on my bike. Its pretty big, but it is so very useful. Holds all my "essentials" (plug/inflator kit, small tool kit, rain gear, 20 oz water, portable charger/mini jump starter, spare USB-C cables), then when I get to the store it holds my helmet (2XL Neotec II - big head), Zumo 2, X3 camera, and my gloves while I grab groceries. When I come back outta the store, in addition to my essentials, it holds several days of groceries and supplies.For content security, I doubt it will keep a determined thief out (kinda like car windows), but it will definitely keep crimes of opportunity at bay during the day.It bolted fairly easily to my tail rack and seems quite secure. The mounting plate is pretty heavy-duty. I have a NiceCNC tail rack that allowed me use 5 screws/nuts/washers (both sides) to bolt the mount to it. I did have to remove the tail rack to attach it, then bolt the tail rack back on the bike.Things I really like about it ...1. I love the size (65L model) - no more toting a backpack or tail bag, plus helmet, plus all the extras when I get off my bike while running errands and such.2. Plastic corner bumpers for protection and reinforcement3. Plenty of tie-downs on top of the box for Rok-Straps or a net. A net on top is super handy for wet rain-gear after the storm passes.4. Interior padding and straps5. Held up to a garden hose spray test to the sides with no leakage through the gasket.6. Costs about 3x-4x less than the big name brand top boxes and seems almost as nice.**I wish I would have bought this before I purchased my other 2 tail bags**Things I don't really like about it ...1. Plastic Hinges2. Heavy Chemical odor when I first got it. I let it "air out" in my garage overnight. Seems OK now.3. Slightly soft bolts. Bring a bolt and one of the self-locking nuts to your local hardware store and ask them to find you some hardened replacements. Might not have them in hex-head, but that should be OK if they are deep Phillips.4. The one I received naturally closes just barely off-center. I just pull the top latch with one finger when I close it so the latch lock catches it in the center. Doesn't bother me enough to exchange it. It still passed my water test.A note ...A few other reviews said the entire box is plastic and not aluminum. Well, the hinges and protective corners are certainly plastic, but for the corners that's a good thing. Plastic absorbs more shock than aluminum. However, the box itself (sides, top and bottom) are most definitely coated metal (and likely aluminum since its fairly inexpensive). You can test this unscientifically by "feeling" how cool to the touch the different parts feel.An Almost-Science lesson ...Plastic is an insulator. Metal (aluminum) is a conductor (moves energy). When you have metal and plastic that have been sitting the same room for a long time, the temperatures are equalized - they are physically the same temperature. However, when you put your hand on the plastic, then on the metal, the metal *feels* much cooler. The plastic (insulator) resists the heat from your hand (virtually no energy transfer), thus, it feels about the the same as the ambient temperature in the room. The metal, however, immediately starts to absorb and move (conduct) heat (energy) away from your hand, making it *feel* cooler to the touch. This box definitely exhibits this behavior in my garage. The sides and top of the box *feel* 15F-20F cooler than the plastic corners and lid rails.One more thing ...I almost forgot to mention no one has thrown any cabbage at me that I noticed and I have not 'aggroed' any bears ... or at least they haven't caught up to me yet. Also, I have not noticed any "drag" and my fuel economy is no different (about 58mpg US with or without the box).
