I bought the Polaris Click 6 harness from the dealer when I bought my 2018 1000 XP and they installed it. I was told by others to beware because if you go on your side or upside-down, the buckle may not release. A year ago I was on a night ride and it rolled, slowly onto the passenger side. I COULD NOT RELEASE THE BUCKLE! My weight was putting pressure on the belts due to hanging in the harness. I tried to pull myself up by the roll cage to reduce pressure, but the buckle would not release. I was with others who righted me and the harness worked properly as soon as I was up righted. I then put a seatbelt cutter in it my RZR. Last month I was doing a water crossing and it rolled onto the drivers side, which completely submerged me under water. I could not get the buckle to release. I grabbed the belt cutter and as I was starting to cut the belt, a friend came over and was able to release the buckle. I immediately replaced the belts with a quick release harness. I contacted Polaris and they said the belts would have to be reinstalled on the RZR and checked by a dealer. The belts were checked a couple of years ago due to a recall. I am not going to reinstall the belts just so Polaris can say they are OK. They are NOT. Please consider being on your side, upside down, in (under) water, fire, or medical emergency and the buckle will not release. They are very comfortable, but not worth dying over. I never considered drowning in it, but this was in Moab, UT.
