Bought this for my Kodiak 700 EPS. Installation was relatively easy and I just came back from a 3-day ATV trip on the Outlaw Trails in Southern WV. The box worked fine and stayed largely dry and dust free on the inside due to the weather stripping I had applied (suggested by earlier reviews). Can't understand why the manufacturer wouldn't install weather seals themselves, seems like a no-brainer. The lock can be a little tricky at times but generally works, the two elastic bands that help keep the lid shut are great.

A couple of minor irritants. 1. The box has no dividers, it would have been nice with a bit of webbing or anchor points for dividers. 2. the top of the anchors stick up and will have to be covered by something (rounded nuts would have been nice) or they may rip stuff or (in my case) puncture beers. 4. the seat is not removable for when you are driving alone or transporting on a trailer.

Other than that I'm quite happy with the purchase, it's a sturdy box, it looks good and the price was great.

Bolted up nice and tight on 2018 Kodiak 450. The seat matches in color and super comfortable tons of space. I'd love to have seen the larger compartment separated left and right so I can throw cold drinks and ice in one side but my spray foam skills will take care of that :).
The clearances are professional and the plastic is rock hard there's no cheap flimsy flexing going on this thing is way better than another product I purchased for $160 that holds two helmets. I strap mine to the rack anyway.

Nice half inch lip to stop water creeping in and the keyed entry is a nice touch to stop my buddies from drinking my supplies.
Also the grab handles work perfect for a passenger so they don't have to hold onto you.
The arm rests are contoured for a male with broader shoulders. Women and small children may have a fitment problem when it comes to that one thing but my passengers have no problem reaching the grab handles and it's still comfortable.
Seat is plush and backrest is perfect height.

Works good and the price is right however there should be padding on the arms, wife complains about the hard plastic and the angle of her arm to the hand guard. The latches are nice and easy, like that it has a lock, with the whole cap coming up it does make it easier to stuff crap in there but at the same time my last seat had the individual arms come up as storage and the wife could reach in and throw me beers while were riding. With this one I have to wait until &/or stop to drink a beer. Inconvenient because I stay thirsty.

Plastic seam broken upon arrival. Box had no obvious damage so I do not believe it was damaged in transit, I think it was just made very thin, cheap plastic. I am still going to keep it because I broke down the box after getting and didn't see the flaw until after installation, but it being broken before even being mounted rubs me the wrong way. Plastic is very thin walled construction, I don't expect it to hold up to any crash. I was also under the impression you could pivot the lid on the spring retained pin but you have to take the pin all of the way out and the back of the case all the way off to get the gun out. Mounting hardware also low grade steel that bent after barely tightening. Over all I would not recommend this product. Epoxy will be my next purchase.

I got 2 of these for our 2016 sportsman 450 and 570. I did not want to permanently install these and did not want to buy a metal rack so I found these toggle anchors at Home Depot. 2 for $10. They are rated at 333 lbs and with 6 of them on each the seat in in tight. I did have to install some 3/8" washers due to bolt is a tad bit too long. My 10 and 8 year old daughter love riding in the seat. We also bought foot holders on amazon for stability when trail riding. Hope this helps fellow Polaris owners.
