I have the other version of those, and they're okay. The cord rope is a little too big to fit comfortably within my smaller hands.... and they're a bit too long for my Racking Horse's neck so I really didn't use them often. They hold up okay on trails, the clips however sometimes get jammed and you gotta watch that you keep them "swiveling" properly so they don't snap. The cord is pretty strong itself, it hasn't stretched or thinned out at all and only has a few scratch marks from getting brushed in trees.
Overall, they're pretty good for their price :) I also have the matching headstall, I wouldn't trust it on a horse that likes to fit the bit, but it is very decorative and has worked wonderfully for my soft-mouthed mare for the past 2 years. Hope that helps!
