Review on 🧳 VMSTR Travel Vacuum Storage Bags with USB Electric Pump - Medium Small Space Saver Bags for Travel and 3D Printer Filament Storage Kit (8 PCS) by Jennifer Phillips

I travel quite often and don't want to check bags so I was hoping these bags would help free up space in hand luggage. Pros: The pump works well, albeit slow due to the size. Squeeze excess air out of the bag before using the pump, then use the pump to further seal. When the valves work they work great and the bags come together in a really tight package. Cons: valve. The valve did not work on about half of the bags, especially on bags M 12.6 * 10 inches. I could hear air coming out of the valve. Back then, it was no better than a zip-lock bag. If you buy, then for the pump. Brilliant. When the pump is not needed. Do not buy!
