I use them, and love them. I put my quilts and pillows in them to store during summer months. Also sweaters. No smell. you have to be sure there are no holes tho or it will leak. it really does a great job, and I reuse mine over and over till they leak. its great to take on a trip as well, that way you can fit twice as much in your suitcase. I have ones that you put the item in, and then roll the item to squeeze out the air. love them!
