Any new product takes time to carefully read the instructions and apply those instructions when trying for the very first time. As far as product longevity, each kitchen machine needs to be operated within the scope of its manufacture. I think this will be a very good addition to my kitchen for several reasons. Food prices are at an all-time high and keeping them fresh in the freezer, bulk spices in the pantry, and even some fresh vegetables in the refrigerator, having a vacuum sealer is huge. My friend who is a chef in his own rite, grows a huge garden every year including spices, and does a lot of canning told me this was essential. I don't know how many times freezer burn as occurred over the years, but zip-lock bags are totally wrong. Secondly, research is always key, not just going to one review source but several. Everyone has their price range, but I try to buy the middle. If it's too expensive, a waste of money; or not enough money, the risk of the appliance failing is that much greater; or not enough features to do a myriad of chores. Finally, I think all vacuum sealers can work, but getting the right one for your kitchen and use, at a price that's affordable to you, and what you're going to use it for, only you can decide. But for a median price and great features, I think this Nesco VS-12 will do just fine. Happy sealing! Review Update, 2/5/2023 Now that I've used this Nesco Sealer, I am prepared to render my final review. Absolutely a great vacuum sealer. Packed with all the features an average cook needs to keep food freezer safe and lasting long periods, this one product needs to be in every kitchen, great and small. It's simple economics. Food today is more expensive and, it's becoming scarce, with all the viruses that attack livestock and our food supply; and preserving food that is on sale, this is an essential kitchen tool. For all families, from 1 person to many, maximizing the food budget requires common sense and the right kitchen tool to make that happen every month. As a senior retired person, I cannot afford to waste anything, least of all food. Even young families, middle-aged people, and any person who still works and buys food needs to be thinking about a good vacuum sealer. Unless you are rich and famous who have all your meals prepared and doesn't care, this review is not for you. I'M speaking to those who WORK, or worked for a living and know the value of what they buy. Maybe you have money to burn, I do not, therefore my recommendation is: Nesco is a great vacuum sealer for the price. Do not let this bargain slip by. Trust me, time well spent in the kitchen reaps huge dividends in the grocery budget! And I really mean, Happy Sealing.
