I have one, had it for a few years.
I based my purchase on knowing where the winch came from. As you know there are many winches around, many of which can only be rebadged winches from ..... somewhere, most likely China. Because we don't know who manufactures them you can't find out anything about them.
Runva winches do come from China, they specialise in winches and you can Google them to find out more.
I like knowing what I'm buying.
And welcome to forum, hope you enjoy it.
