Great quality. I had to replace the strap, but over all very happy with it.

Got it installed yesterday. No issues at all other than i needed to go get longer bolts to go through the mounting surface. Heavily built for the 3500lb capacity. You do have to unbolt and move the handle toa different set of gears to change speeds, which is alkward, but common to almost every hand winch i've ever seen. Other reviews mention that the handle is on the "wrong" (left) side. Lol . . .Remove the spool, pop the C-clips out from the gear shafts, flip the shafts around, put the c-clips and spool back in with the gears on the side you want the handle on. It's basic mechanical engineering, folk! Be careful popping the c-clips, as they will fly far and wide. You can get replacements at the local hardware store if your land in the grass like mine did . . . .

Just what I needed. Fit perfectly in place. Love the two gears making it easier to pull a heavy load.

Had high hopes, but product was unusable. See attached pictures, on its very first use, several teeth on the small gear and large steel gear broke immediately. Large steel gear started rusting immediately. This was at a deep water ramp, only have to move the boat about 6 inches to lock it into the bow support. Boat only weighs 1500 pounds. Unfortunate.

Works great, but the handle fell off on the maiden voyage, and I’m having a very hard time finding a replacement handle..

Works as expected. I replaced my winch that has been on my boat trailer for 30 years and this one seems to be better quality. I can’t tell if the heavier materials are compensating for low build quality, or if everything is over built for longevity, but I like it so far. Having a forward and reverse function, while not necessary for my application, is a really nice touch.
