Nesting liners... how long do they last? Worth the price?

@Panhandler80 Yes, excelsior mats. I think mine were from Precision Pet, but hey look the same.

The ones I posted a link to? Thanks.

Everything I described was about excelsior mats. I just looked back in my Amazon history. I bought theses: https://www.amazon.com/gp/product/B00CAVMIK2/, so not the same exact ones but they look pretty similar to me.
