UNERVER M11 Electric Mason Jar Vacuum Sealer Kit - Vacuum Sealer for Wide & Regular Mouth Canning Jars

I recently purchased the M11 Electric Mason Jar Vacuum Sealer and I am extremely happy with my purchase! The device is compact, easy to use, and works perfectly on my mason jars. It creates a strong seal that keeps my food fresh for much longer. I love how quick and efficient it is, and the included accessories make it even more convenient. Delivery was smooth and on time, and the product worked right out of the box. I highly recommend this vacuum sealer to anyone looking to preserve their food with minimal effort!

This does a great job removing all the air from the jars, the suction is great. Operating it is very simple, just two buttons, one turns the vacuum on, and one turns it off, that't it. It came fully charged and I haven't had to re-charge it yet after four batches of canning. I have to say that I have not only used it with Mason jars, but also with Ball jars. Good product overall.

I have been using this for a while for seal my salad veggies in mason jars to extend the life. I'm so surprised how long they are lasting. I've had bell pepper etc in them for 4 weeks now and they are still good. I take what I need and reseal the jars back up. I do let it go until it automatically shuts off, 120 seconds. I have found the veggies from the cabbage family ferment rather quickly. I started to open the cabbage and the seal flew off from the built up gases. I still use it for them but I only run the vac for about 50 seconds.

Could it automatic shut off?But it don't

I bought the M11 Electric Mason Jar Vacuum Sealer Kit and it’s quickly become one of my favorite kitchen gadgets. It’s compact, cordless, and incredibly easy to use—just place the sealer on the lid (it works with both wide-mouth and regular-mouth jars thanks to the included adapters), press the button, and it pulls out the air in seconds for a solid airtight seal. Overall, excellent value, works reliably. Highly recommend.

Better than the actual Mason genie that cost double what this does. Better quality, easier to work. Buy this!

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. I’ve 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. I’ve 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 it’s 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, they’re completely optional. The vacuum itself is strong and consistent, and it’s clear that this product was designed with real-world use in mind. The build quality is excellent, and the design is very intuitive. It’s compact, easy to handle, and doesn’t require bulky machinery like a traditional vacuum sealer with tubes and a mason jar attachment. I’ve 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. It’s 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 isn’t 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. It’s also great for organization. Your pantry looks neat, and the jars stay sealed tightly without fuss. Overall, I couldn’t be happier with this purchase. It’s 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: I’ve 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.

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.

Very easy to use,I put fruit,nuts,museli in masson jars,im not a canner,but I live alone so a bag of walnuts or museli from Costco can last me a long time,and I want things to stay fresh, so this little device is brilliant, I'm glad it has the little gadget to remove the lid after,because I have arthritis in my wrists I wouldn't be able to get the lid off with out it, the seal is that good,definitely a handy product, i would recommend this product.

Me funcionó muy bien, y después de bastante uso sigue funcionando.

travaille bien et beaucoup plus rapide que de placer tous ces pots dans un chaudron pour les faire sceller. Moins de perte de temps et pas besoin de faire bouillir.

⭐️⭐️⭐️⭐️ - Efficace, mais avec quelques nuances à connaître J’ai acheté cette machine à emballer sous vide électrique pour mes bocaux Mason Jar, et elle est globalement satisfaisante ! Voici mon retour détaillé : Facilité d’utilisation : Super intuitive, elle fonctionne parfaitement sur les bocaux à ouverture régulière et à grande ouverture. Appuyez sur le bouton, et le vide est fait en quelques secondes. Compatibilité limitée : 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 à forme ronde. D’après mon analyse, leur rebord ne permet pas au produit de bien "s’asseoir" pour créer un vide efficace. Couleur conforme à la description : Bien que la couleur diffère légèrement des photos, après vérification, c'est conforme à la description. Je le prends donc comme une erreur de ma part. Autres observations importantes : Charge et autonomie : Le produit doit être chargé pleinement avant la première utilisation. Cependant, il est difficile de savoir combien de temps cela prend. Heureusement, chaque cycle consomme en moyenne seulement 5 % de la batterie, et l’appareil indique le pourcentage de charge restant. Le bouton "Stop" permet d’interrompre à tout moment, et l’appareil s’arrête automatiquement après 120 secondes. Rapidité et précision : J’ai adoré la rapidité et la précision de l’appareil. Il affiche même le décompte en secondes pendant l’utilisation. Durée de vie : La durée 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 vidéo de démonstration montre la conservation de sauce à spaghetti sur une tablette. En tant qu’ancienne professionnelle de la restauration, je ne recommande pas d’utiliser cet appareil pour ce type d’aliments, car cela ne respecte pas les normes de sécurité alimentaire pour des produits périssables non réfrigérés. Malgré ces nuances, je suis vraiment satisfaite de ce produit. Son efficacité et son utilité m’ont impressionnée, et je l’ai utilisé dès sa réception. Je recommande ce produit pour les amateurs de conservation maison avec quelques précautions en tête !

Vraiment un produit qui étonne. Après avoir utilisé tous les couvercles inclus, j'ai utilisé de vieux couvercles Bernadins et le résultat est le même: bonne étanchéité. La première charge permet de faire plusieurs pots. En 120 secondes les aliments et fines herbes se conservent parfaitement. À titre d'exemple, mes fraises achetées chez le fermier il y a 7 jours sont encore fermes et savoureuses.
