I just came from the shop and saw that the box from one of the winches that crapped out on me was for a Viper, both were Vipers actually. The winch really gets a work out plowing. Up and down several dozen times per plow and in an average season, probably 3-4 times per week. So perhaps for less rigorous use, they are just fine as being reported, but can for sure say both of mine crapped out on me quickly, while the Warn is still going (knock on wood!).
I can also say that the Viper and the Warns were nearly identical looking from the outside, even the relay and toggle switch. The only difference I could see from the outside was the mechanism that lock or lets the spool run free. So looks like one is copying the other.
Oh, and both Vipers started to rust out in spots, while the Warn does not have any rust. Not trying to start any kind of argument, just reporting my experience. I did love the Vipers when they were working though! Just got fed up with them crapping out and leaving me without a way to lift my plow while in the middle of a snow clear.
