Review on Jumbo Vacuum Storage Bags (6-Pack) - 80% More Clothes Storage Space | Compression Seal For Comforters, Blankets, Bedding, Clothing | Great For Closet & Travel Use With Pump Included. by Earl Ton

One 40” x 30” bag held several thick microfiber and "tapestry” type throws that I’m not using right now but I want to keep them for future use. They’re thick and bulky; I think I put seven of them in one bag. It’s flat enough to slide under my bed or couch so storage is easy and dust-free.The hand pump included was totally useless. No instructions with it but seemed like no brainer: remove the cap on the seal, screw on the pump, then pump the handle up and down. After several minutes I didn’t see any results at all so I put it aside and used my vacuum cleaner.And a note about that. I have a Shark Navigator Lift-Away (a few yrs old) and it doesn’t have a nozzle that will fit this bag’s valve. Fortunately I saved a connector from another vacuum from long ago thinking it might come in handy one day. Today was that day. It slid right on the vacuum’s hose end while the smaller end was the perfect fit for the valve on the bag. It worked great and the bag was deflated in seconds. So maybe keep that in mind and check to see what your vacuum has. I attached two pictures of the adapter I used as well as two pictures of the size of the valve opening using a ruler. Your vacuum hose needs to fit snugly around that.Also not very clearly pictured is a clear round tag that I dated and attached to the bag. That will let me know how long the bag stays sealed. I didn’t want to start marking on the bag as I expect to reuse it multiple times. I can peel the tag off easily but that’s not a big deal if you don’t have anything similar. You could use masking tape, etc., if you wanted to do the same.The bag does seem sturdy and the zip closer is strong but make sure it’s closed tightly. I pressed firmly and ran my fingers over it end to end several times to make sure it was sealed. The cap on the valve is very easy to use and screws on quickly so no air gets back in the bag. Make sure you screw the cap on straight; if it goes on crooked it will let air back inside the bag and reinflate.Right now I’m happy with it but time will tell. I gave it four stars on easy to use because of the pump. If anyone knows "the secret” to that or what I might be doing wrong, I’d be interested to know. The pump would be great to take on a trip along with some smaller bags as it’s plastic, very light, and only about 9-1/2” long. But not so much if it doesn’t work.I’m curious to see how it holds up long term.
