I've been using the Clorox Toilet Wand for years and have bought numerous boxes of refills without problem. However, the last box of refills I purchased was useless. The sponge was barely attached to the plastic part that attaches to the wand. As soon as I tried to use it, it fell off. I checked the next refill and could easily peel it away from the plastic with very little effort. They were all unusable. I can't give you the box number for this product because I dumped them into the the dispenser as soon as I bought it, and before I knew there was a problem. Now, I'm wondering if I dare buy another box of refills or not, as I don't want to waste my money again. Thank you.
