Review on Hanging Vacuum Storage Bags Space Saver for Clothes, 4 Packs - Long 53x27.6 inches, Vacuum Sealed Bags for Suits, Dresses, Coats, or Jackets - Closet Organizer and Storage Solution by Candace Young

We received them on February 28th and have just started packing the closet. I filled the saver bag with my coat, sealed the side and checked again as I wasn't sure if it was sealed. Then he turned on the vacuum cleaner, which collapsed but didn't crush the clothes. I returned to this bag after about 15 minutes and all the suction was gone. So check the tightness (three times) and pull the vacuum again. Couldn't come back to check again for 45 minutes and it lost vacuum again. Didn't get a chance to check another bag because we had a lot of energy and started packing other things. If I check tomorrow and the situation is the same, I'll be happy to send the batch back. I won't say don't buy them because without a vacuum they still look like good dress protectors if you can sacrifice the bag's main function of saving space.
