Even though some have complained that these Wraps are plastic, they are very rugged plastic and I do not see them breaking easily. They will work well until I decide to replace the existing system with a more expensive setup. The only issue is that I had to call many times and email multiple times before I finally got someone to confirm they were in stock and got them mailed to me. I purchased them 3 weeks before a trip and received them the day I was leaving. So allow a lot of lead time if you need them quickly.
