Product seems to work well… I was able to hang it from a 1/2” eye bolt, and lift my 490# boat… it is a little slow compared to my harbor freight atv winch (which I hung in my attic for lifting) The worst part about it is the reaction time… when you click the up/down button… it’ll lift… but then when you let go, there’s a half second where it continues it’s action… so it makes putting my boat down gently a bit of a challenge… other than that, no issues… has a remote with a special battery size to it, looks like it’s half the length of a AA battery… remote works well
