Milemarker manufactures fine hydraulic winches but I wouldn't touch their electric winch line. They started importing them from China once sales of their hydraulic winches dropped way down once people started complaining how slow they are, and speed can be important on the trail in some situations. I no longer trust the specs on Chinese manufactured electrical products like I once did. And I don't trust that the specs on that Milemarker winch are nearly as good as claimed for various first-hand reasons like below.
For just one example, I bought a Chinese made Chicago (funny brand for a Chinese made product) bench grinder from Harbor Freight a few years ago. My 25 year old 2/3 HP Craftsman bench grinder finally gave up the ghost and smoked its guts out one afternoon. Sears didn't have any more Craftsman bench grinders and I needed one that day so I went over to Harbor Freight. They had one that was a bit larger than my Craftsman and it was marked as 3/4HP, slightly more than my Craftsman had. With high hopes of even better performance due to its claimed slightly higher HP, I plugged it in and turned it on. The first thing I noticed is it took a long time to get up to speed, unlike the Craftsman that was at full speed within a second or two at the most. The Chicago takes a stupid long time to get spinning at full speed. Then, despite its claimed 3/4 HP, it bogs way down to the point of stopping when just using it to wire brush anything. It has no power, I have learned to turn it on as soon as I know I'll be using it and to not push as hard as I'd like to against its grinder or wire brush.
For anyone thinking you can believe all the published specs, you can't.
