M11 Electric Mason Jar Vacuum Sealer Kit - with Wide and Regular Mouth Mason Lids, Got this yesterday and I am pleased. Bought this one over the other by the same brand because it said it would seal over the counter mason jar seals rather than speciality seals. Seems solidly built and should last a long time. Charged it immediately and tried it out. It seals over the counter seals perfectly. They should hold their seal for a long time if there are any problems I will update. Update: It can be finicky. I have one lid and one jar that will just not seal regardless of what I try. If I use a different lid or jar it seals fine. Go figure, but overall I am still very happy with the purchase.

I wanted a tool that would help me keep my veggies fresh for a long time and this mason jars was the solution. Easy to use and rechargeable

Amazing! Keeps veggies fresh for a VERY LONG time! Sealing your mason jar has never been so easy! Clean jar, veggies in, place the sealing lid on and put the sealer on…push the “ON” button and wait for 20 seconds and that’s it you’re done! Game changer for meal prep, grab n go salads the options are endless. Love this product!

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.

This was a gift for a friend. she does a lot of canning. I also have one and found it satisfactory

Très satisfaite du scelleur à pot Mason. Je viens de le recevoir et tout juste utilisé. Comprend un chargeur pour port USB, des couvercles, des autocollants, le gadget pour ouvrir les bocaux.. à date il fonctionne bien et scellé en 30 secondes. J'aime le minuteur affiché

Reçu assez rapidement , fonctionne bien sur les pots Mason classique, bien que utiliser que peux de fois environs 6 fois avec les gros pots pour empêcher l’avocat de noircir , pas encore utiliser pour faire des conserve , je reviendrai pour la fiabilité et la durée de vie du produit . Petit bémol le fil pour la recharge ne fonctionnait pas heureusement j’en avait un mini USB Après de multiples essais, je suis vraiment satisfaits fonctionne vraiment bien , la durée de la batterie est bonne 👍
