The air releases out of these after a while. They also rip easily, so not very good if you reuse them often. I found a cheaper version on Amazon that works better and the plastic is more durable.

I'm usually not too big on buying all name brands but ziploc is one of those things that is just better than the competition. Perfect for moving!

I use this to put away my seasonal clothes away and it fits great under my Queen size bed. Great idea and eliminates space.
