MagicBag Large Heavy Duty Vacuum Storage Bags, 3 Pack Flat Compression Bags for Clothing, Space Saving & Airtight

I rarely give a 5 star review, but this item deserves 5 stars. I was very hesitant to spend the money for these vacuum seal bags, for fear I would get junk and would've wasted the money. I'm so glad I gave this a chance. I fit a king size comforter in one of the heavy duty large bags. It was a little difficult getting the comforter into the bag %26 that process did result in me popping the zipper off, but once the blanket was in the bag, you just pop the zipper back on and it sealed very easily. Using my regular vacuum cleaner hose, I easily sucked the air right out of the bag. I did press down on the bag to help push extra air out / flatten it down but I definitely didn't need to do that. It works well all on its own. It's been about an hour and the bag remains completely sealed, where some people have reported that the bags slowly let air in. We're moving soon and a lot of our items have to be stored until we expand the home and it's important to me that our extra clothes and extra bedding are not ruined while in storage. I'm confident these bags will work well.
