Detailed Review!! 5/5 Stars
I have been using this mason jar vacuum sealer for several weeks now, and I have to say, it has completely transformed how I store my pantry staples and dehydrated foods. Iâve used it about 50 times on different jars with a variety of contents: everything from beans, rice, oats, and flour to dried herbs, nuts, and dehydrated fruits. Not a single jar has come unsealed. Iâve been watching them closely, and the vacuum holds perfectly every time. One of the things I love most about this sealer is that it works on just the lid. No rings are required, which makes the process much cleaner and simpler. The lids seal tightly on their own, and itâs easy to see when the vacuum has done its job. For those who want extra peace of mind, you can absolutely use the rings, but in my experience, theyâre completely optional. The vacuum itself is strong and consistent, and itâs clear that this product was designed with real-world use in mind. The build quality is excellent, and the design is very intuitive. Itâs compact, easy to handle, and doesnât require bulky machinery like a traditional vacuum sealer with tubes and a mason jar attachment. Iâve used it on half-pint, pint, and quart jars, and it works flawlessly every time. I've done both wide and small mouth jars as well as experimenting with sauce jars and other solid lid jars. Itâs perfect for anyone who wants to extend the shelf life of dry goods without investing in a large vacuum sealing machine. Important warning about canning thats concerning in these reviews: This product is not intended for canning food to make it shelf-stable. It is only for dry goods and dehydrated foods. If your goal is long-term preservation of perishable foods like vegetables, fruits, sauces, jams, or meats, you still need to use proper water bath or pressure canning techniques: Water bath canning is ideal for high-acid foods like jams, jellies, pickles, tomatoes, and fruit preserves. The jars are boiled in water for a specific amount of time to kill bacteria, yeasts, and molds. This process ensures the food is safe to store at room temperature for long periods. Pressure canning is required for low-acid foods like cooked beans, meats, vegetables, and soups. Because these foods can harbor harmful bacteria like Clostridium botulinum, boiling water alone isnât sufficient. A pressure canner reaches higher temperatures that destroy these bacteria, making the food safe for long-term shelf storage. Using this mason jar vacuum sealer on its own will not make perishable foods safe for room-temperature storage. However, it is perfect for keeping dry goods, dehydrated snacks, grains, beans, nuts, flour, herbs, and spices fresh and protected from air and moisture. Itâs also great for organization. Your pantry looks neat, and the jars stay sealed tightly without fuss. Overall, I couldnât be happier with this purchase. Itâs reliable, easy to use, and has quickly become an essential part of my kitchen. If you want a simple, effective way to extend the life of your dry goods, this vacuum sealer is absolutely worth it. TL;DR: Iâve used this mason jar vacuum sealer about 50 times on a wide variety of jars, and none have come unsealed. Works with or without rings, easy to use, and perfect for dry goods or dehydrated foods. Not for canning perishable foods. Use water bath canning for high-acid foods and pressure canning for low-acid foods to ensure safety. Highly recommended for keeping pantry staples fresh.

The sealer is the real deal!
This vacuum sealer is a game-changer for my food storage! I love that it's so easy to use - just attach the sealer to the top of a mason jar, press the button, and watch as the air is sucked out of the jar. And unlike other vacuum sealers I've used, the lids on these jars can be reused again and again, which saves me money and reduces waste. The M11 sealer is also really versatile. I've used it to seal everything from dry goods like flour and rice to leftovers and even liquids like soups and stews. It's perfect for storing food in the fridge or freezer, and I've noticed that my food stays fresher for longer when I use the M11. Overall, I highly recommend the M11 Electric Mason Jar Vacuum Sealer to anyone looking for an easy, efficient, and environmentally-friendly way to store food. It's well-made, easy to use, and a great value for the price. D

Works great and no more bugs or stale food!
I got this for cheap after viewing the $60 one on my feeds. This works great! I use the wide mouth mason jars and now no longer have moths in my cereal/flour/breadcrumb cabinets. I did a ton of jars, I'd say 35, before it even needed charging. You vacuum seal for about 50 seconds each time, it doesn't shut off automatically so be careful. I did try it on some tiny mason jars, like sample jelly ones, and it didn't seal with the smaller part. That's okay, it might have been too small or warped edges (old jars.) I love seeing the product inside the jars and they stack great in my cabinet. It comes with a charger (no wall socket) and a little jar opener, which we use, although you can pry it off with a thumb if necessary. No more stale cereal too. Haven't tried it with berries or veggies in the fridge yet. I don't usually use the rings from the mason jars unless it's something I don't get into often. Edit: I had to take off a star because it stopped working, only the timer works. But it more than paid for itself in the two months I had it.

Great to have seal/preserve food in jars.
This is one of the best gadgets I have my kitchen. I have it in use almost every day. It seals up the jars of food - from brown sugar to rice to dried fruits and veggies to fresh fruit, the list just goes on from there.

Good Product
I love this! Unfortunately, I got it wet inside and it stopped working. Also I saw some people give bad reviews because they said it stopped sealing. Here is a tip: Once you put the sealer on, continue to twist it to make sure the lid is seated correctly in the sealer, then turn on the sealer. Took me a few times to figure it out.

Glad I bought. Well worth it for individual use.
Bought as Christmas gift for myself. It works really well. Bought quality jars with lids and things. My own issue is that I have a chronic wrist injury, so isn't always easy to get this unit off the sealed jars. Tried the small jar sealer portion recently, and it was not easy. The larger jar size is much easier. I'm sure it will be easier on both of them once I get the hang of it. Sealed vanilla beans, shredded chicken, red sauce, etc. Holds up long-term, and lids pop off without damage.

Powerful, efficient and easy to use!
So far, so good! It is very powerful for it's size and seals the jar vey well. I really like that it gives you a digital readout to let you know when it is properly sealed. It was a nice surprise that they included two sixes of some jar tops, labels and an opener. I ordered this without thoroughly reading the ad, so I was not expecting those included items. It is a very easy and efficient way for me to preserve my conserves. Obviously, I can't comment yet on the long-term durability, but the build and motor seem very solid and powerful. It is obviously not for commercial use. But I am sure, for my situation, that for yearly use it will last a very long time.

La couleur n'est pas exact, ne fonctionne pas sur tout les formats de pots
âïžâïžâïžâïž - Efficace, mais avec quelques nuances Ă connaĂźtre Jâai achetĂ© cette machine Ă emballer sous vide Ă©lectrique pour mes bocaux Mason Jar, et elle est globalement satisfaisante ! Voici mon retour dĂ©taillĂ© : FacilitĂ© dâutilisation : Super intuitive, elle fonctionne parfaitement sur les bocaux Ă ouverture rĂ©guliĂšre et Ă grande ouverture. Appuyez sur le bouton, et le vide est fait en quelques secondes. CompatibilitĂ© limitĂ©e : Attention, elle ne fonctionne pas sur les bocaux Mason Jar de 18 mm (entre les deux tailles standard), ni sur certains bocaux comme les pots de confiture Ă forme ronde. DâaprĂšs mon analyse, leur rebord ne permet pas au produit de bien "sâasseoir" pour crĂ©er un vide efficace. Couleur conforme Ă la description : Bien que la couleur diffĂšre lĂ©gĂšrement des photos, aprĂšs vĂ©rification, c'est conforme Ă la description. Je le prends donc comme une erreur de ma part. Autres observations importantes : Charge et autonomie : Le produit doit ĂȘtre chargĂ© pleinement avant la premiĂšre utilisation. Cependant, il est difficile de savoir combien de temps cela prend. Heureusement, chaque cycle consomme en moyenne seulement 5 % de la batterie, et lâappareil indique le pourcentage de charge restant. Le bouton "Stop" permet dâinterrompre Ă tout moment, et lâappareil sâarrĂȘte automatiquement aprĂšs 120 secondes. RapiditĂ© et prĂ©cision : Jâai adorĂ© la rapiditĂ© et la prĂ©cision de lâappareil. Il affiche mĂȘme le dĂ©compte en secondes pendant lâutilisation. DurĂ©e de vie : La durĂ©e de vie semble prometteuse, mais je n'ai pas encore assez de recul pour confirmer sa robustesse sur le long terme. Conservation des aliments : Une vidĂ©o de dĂ©monstration montre la conservation de sauce Ă spaghetti sur une tablette. En tant quâancienne professionnelle de la restauration, je ne recommande pas dâutiliser cet appareil pour ce type dâaliments, car cela ne respecte pas les normes de sĂ©curitĂ© alimentaire pour des produits pĂ©rissables non rĂ©frigĂ©rĂ©s. MalgrĂ© ces nuances, je suis vraiment satisfaite de ce produit. Son efficacitĂ© et son utilitĂ© mâont impressionnĂ©e, et je lâai utilisĂ© dĂšs sa rĂ©ception. Je recommande ce produit pour les amateurs de conservation maison avec quelques prĂ©cautions en tĂȘte !
