We have had a couple of Vacuum sealers. Was looking for something that balanced cost and quality. The Vevor sealer completely exceeded our expectations and scores A++. The double seal is great. Have not lost a single seal in the past couple of months that we have been using the sealer. It works so well, we started using more often that we had int he past. Today, for example breaded chicken cutlets were on sale for $5 per pound. Purchased 7 pounds, came home and put them in packages of two. We just defrost, including warm water bath to accelerate the process and cook. Ridiculously convenient, and saving money.
