Query: All six of my guests we're EXTREMELY DISAPPOINTED!

I purchased two sets of the can/bottle holders for an outdoor pool party. Sure they looked sleek & assumed they would do a great job (especially being frozen & all of drinks we're well chilled.) After we all had used them, we all agreed...a big waste of money. They do not freeze solid, do not keep drinks cold longer than ~20 minutes-if fact we all agreed that my old foam drink kozies that I purchased for 99 did a better job. We we're even sitting at our shaded patio table with an overhead fan blowing on us. A real waste of money! I read & trusted all those positive reviews. I want to know what they were using? Maybe they were using them in the dead of winter in Alaska. I want my money back!
