Query: very disappointed

Three broken struts in a couple of years. I fixed the first couple with pliars and a piece of a paper clip. Then it went into the trash. The design is great...makes a lot of sense, but the quality of the materials they use are the weak link. They sell these because the design really makes sense, but I was extremely disappointed with the longevity of it, especially considering the price.
