Review on 7 Large Vacuum Storage Bags: Airtight Compression For Clothes, Pillows, Comforters & More - Includes Travel Hand Pump! by Marc Tufa

Ultimately, yes it works.However the product states it has Zip for helping with the sealing/unsealing and it does not. This creates two issues, first how to seal it properly as it's difficult to get both lined up and sealed across the entirety without it missing a section; second is how to open, as the zipper strip is welded to the bag portion and easily tears/separates from the bag, creating potential damage to it when opening it.Lastly, the hole to attach a vacuum to, is hard plastic and no gasket, so it's nearly impossible to get the vacuum hose to seal.Hand pump is flimsy, loud, but gets the job done, though for how long is in question, and takes forever to do.
