I have tested these, attached to branches in my front Oak Trees, where I have a motorized string loop for a Halloween decoration. The spring action is most useful, as to maintain tension and the pully's are of decent size to contain some small multi-strand cord. Last year, I had many failed attempts, and this year appears to be much better.

However, there were no instructions and the roller was plastic. Not sure how long that will last against a medal chain.
