I've had it go both ways ....love then and then some dont work. Nicki +2, I bet you are right that some may be defective. I currently store our sunroom spare couch/bed comforter/pillows and it is doing great. I think the suggestion by spr377 is excellent....I would try that first using the heavy duty lawn bags.....that would be a much cheaper option. I will try that myself...thanks!
I am so sorry about your house. Good luck with storing the items.
