M11 Electric Mason Jar Vacuum Sealer Kit - with Wide and Regular Mouth Mason Lids, Jar Vacuum Sealer for Canning Jars, Vacuum Sealing Machine for Food Storage Black

Works great to easily seal jars, both regular and wide mouth size. I'm using this to prolong food life in fridge. Meal prepping using mason jars. Healthier than plastic, spill proof and jars and lids are reusable. Also starting to seal dry goods in jars. Sealed half an avacado Tuesday, still fresh and fantastic to eat on Friday. Absolute win! Single jar was before I opened it Friday, set off 3 were sealed on Tuesday.

I had my doubts when I first purchased it but was pleasantly surprised at the results! It can be used with small and large mason jars. Just to let you know, if the jar does not hold the vacuum it is not the device but a defect in the surface of the jar where the lid seals to, I had a couple. It is a great way to store food for extended periods and is still functioning properly. I would recommend it to anyone. Just remember cleaning and maintaining the unit is key to its longevity! It is easy to use and made of decent materials.

I’ve used this vacuum sealer for more than a year now and it does such a great job keeping my blueberries fresh! I can put them in a quart canning jar and they can last up to a month or more as we consume. Strawberries don’t do as well or raspberries— but probably extends by a couple of days. The charge last a very long time. I think I’ve only charged it up twice and each time it still had about 30%. I would highly recommend even it only used for blueberries, as they cost $6-8 these days! The photo of blueberries - they are two weeks old so far.

Fast and simple to use. Seems to work well and has a good tight seal on jars

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.

Works really good. Pulls a pretty good vacuum. Strong enough vacuum that you can’t remove lids with your fingertips, you need a tool and when opened you hear that “whose” of air. Only problem I’ve had is when removing from some jars the device separates and leaves the regular size attachment on the jar. But it’s not a big deal, you just pull it off the jar and then simply put the device back together with a small twist to lock it down.

I love storing pasta, rice and leftovers in glass mason jars. This sealer is fantastic at keeping the product fresh and safe. No moisture, no mold, no change in flavor or texture. Fantastic little gadget.

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.

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

I bought the UNERVER Mason Jar Vacuum Sealer primarily for storing dry goods like grains, pasta, and flour that often come in plastic bags that easily tear and let food go stale. This vacuum sealer has been a game-changer for keeping those items fresh longer. I also use it for storing dried herbs and some produce from my garden to extend shelf life and reduce freezer space. The sealer is super easy to use with just two buttons—one to seal and one to vacuum—making the process quick and straightforward. After the vacuum sealing is done, I love hearing the "pop" sound when I open the jars again, which is a satisfying reminder that the seal is tight and the food is preserved. Plus, it’s definitely a better option for storing dry goods in glass over plastic, as it’s safer and more durable. So far, I’m really happy with how it’s worked and I’ve noticed my pantry staying organized and my food staying fresher for longer. Highly recommend it for anyone looking to store dry goods and preserve food efficiently!

Good pricing for such a useful jar sealer, works very well.

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
