This is an inferior product. At $15.00-$20.00 per pop I would expect it to last a while. There is no reinforcement on these and it is nothing more than paper. As you would expect, it doesn't take long for the paper to become wet and soggy and just collapse. Mine last about 4 weeks max performing very well when first purchased but output declining fairly rapidly.
