BEWARE! These bags work as advertised for about 12-24 hours then slowly leak air... We are moving and were hoping these would save us some space but just ended up creating more of a hassle. At first, we were extremely pleased with how tight the bags sealed after vacuuming, then disappointed after filling the bags with blankets, jackets, robes etc. We followed directions on the bag, which was very easy and quick. I guess these bags were really too good to be true... DO NOT waste your money on these!
