CVS review: Maxi pads (9 hrs) long super, 42 pads

Have used this product for years but have noticed lately that the product is falling apart in a much shorter period; sometimes 2 hours. The packaging claims that is 9 hours. I usually change it every 4 hours. There is obviously some defect or they are skimping on something. I love CVS and have never had an issue with their products before. This has been happening over the past several weeks (June, July).
