Dave, in my opinion, leave the cupholder the way it is. No matter how fast you replace those darned things, they will keep pace in breaking themselves. A very poor design. I had one replaced under warranty, then they wanted $60 to replace one. I think the part is about $40. Replacement doesn't look very difficult. I did not bother, though. I don't use these things almost ever anymore. I think this is the best solution. My wife uses it on road trips (when she isn't driving). To me it is not worth $40, especially seeing how easily these things break. So, I left mine with one of the two holders broken and so far the other one is holding up (maybe because I don't use it).

Cheers.
