I have been seeing some very interesting youtube videos featuring this wheel winch. The concept is not only extremely interesting, but seems very sound, at least to me. I am interested in this concept for overland and camping trips where one may go solo. Has anyone had direct experience with these wheel winches? good or bad? Specifically with xterras to get even more perspective.

More expensive than a regular winch...

Any experience with hand winches? I personally would rather deal with a mechanical issue (a hand winch malfunctioning) than an expensive electrical issue
