Well, all I had to do was ask to see that there were replacement holders availble! Silly me. I assumed I could not get them by themselves. Great. I will order three new ones. I did not mention that I had guessed perhaps at some time before I bought this Wave that some toddlers might have stood in the cup holders. The guy I bought from had a couple them. I can easily imagine my kids doing such a thing when they were tots while exploring and climbing on anything they could. That would surely tear them along the sides that had only a sight overlap on the heat weld. A 12 or 16 oz bottle weighs a lot less than a 25 pound youngster. Anyhow, it is just a guess since I will agree with you that they should not have worn out so soon. Thanks, Matt!
