I had some king sized blankets to store, and these bags worked great. Yes, the hand pump does take some time to vacuum out all the air, but the bags have stayed sealed for weeks now

I had a good experience with these bags. Although there were a bags that didn't seal properly I think it was probably because I didn't follow the instructions carefully enough. It's important to have a workspace fill the bag correctly and make sure the seal is secure by running the plastic piece across multiple times. I learned my lesson after two attempts but the rest of the bags worked fine and still offered great protection for my belongings.

It is highly recommended to seal the bags. I took care to securely close the ziplock part using the attached slider and my fingers. This step is likely the factor behind any reported issues of leakage mentioned in other reviews. These bags are a blessing especially during the summer when I need to store my comforters. The sized bags are a perfect fit for my queen size comforters and its really satisfying to see them shrink as I remove the air.

I have to admit something; a few bags in the pack had difficulty sealing properly. It was a bit frustrating at first. Most of the bags worked just fine. Keep in mind that the price reflects the quality so even though not all the bags were perfect the ones that did seal provided storage solutions. Just remember to check the seal before storing them to avoid any unpleasant surprises.

Sealing the bag, removing the air with a vacuum and you're done, these bags are extremely easy to use. They have made packing a breeze for my move. Definitely recommended!
