Good but some small issues
While way thicker and seemingly tougher and more flexible than normal zip ties the rubber tracks on the inside break off easily after or during the first use and then kinda squish out to the sides. Another issue I found is that every few of the ties would not actually stay tight and hold in places. They wouldn't positively engage on the spot you want and would loosen up a couple clicks. We'll see how they hold up over time otherwise.
Thanks for the feedback and detailed review. We appreciate your time.
