I looked at it for several days, kind of afraid to try it. Then I did my first one, an open avocado, and it wasn't brown the next day!! That's a win in my world. So, now I am trying different things. The tutorial was what gave me the boost to try it instead of look at it. Very complete explanation! Will probably be giving some as gifts as long as I continue to get along with it.

Kept my strawberries fresh as the day I brought them home
Usually they start to lose their color and become dull within a couple of days. This kept them gleaming fresh until they were all eaten!
Emery G.
A kitchen must have!
I got sick of buying super expensive berries and watching them rot in my fridge in two or three days. Removing the air gives you longer-lasting freshness. I've saved money by not tossing berries just days after I bought them.

I'm sold on it
It works very well. Bean sprouts that usually liquify within a few days look as fresh as the day I bought them 7+ days ago.
Margo F.
Keeps them fresh forever
We bulk buy a lot of different flours, beans, granolas, sugars, grains and herbs. Needed a way to store them for long periods of time, and this was it.
Victoria E.
Best impulse buy ever
I don't know how I went so many years without one of these! I put all my dried goods in jars and seal with this and they stay fresh forever.
Daisy Y.
No more stale crackers
I was a bit dubious that this would work, but sure enough it creates a super strong vacuum! I've been using it on crackers and things we don't eat quick enough before they usually get stale. Love it.

Frequently Asked Questions
Can I use the mason jars and lids I already have?
Yes. The Mason Genie works with any standard regular- or wide-mouth mason jar — Ball, Kerr, or store brand.
Use the included chalkboard top lids, or your own store-bought lids with the included lid adaptor. If it has a lid, it seals.

How long does it take to seal a jar?
About 30–60 seconds per jar.
Set the Mason Genie on top, press once, and it stops automatically the moment the jar is airtight — easier than screwing on a lid.

What foods can I preserve with it?
Almost anything: dry goods like rice, flour, beans, nuts and coffee; fresh produce and greens; leftovers; homemade sauces, dressings and marinades.
Leave about an inch of headspace and it even handles liquids.

Can I use it for canning?
Canners commonly utilize the Mason Genie™ to seal all their dry or dehydrated goods stored in the pantry.
However, it's important to note that while Mason Genie creates airtight seals suitable for preserving foods in mason jars, it is not a replacement for canning or the long-term preservation of perishable goods. Proper canning requires specific heat processing methods to ensure food safety and preservation.

How does it charge and how many seals per charge?
The Mason Genie is cordless and recharges over USB-C with the included cable.
A full charge is good for roughly 200 seals, so most households only charge it every few weeks.

Can I buy the Mason Genie on Amazon or in stores?
Nope — the only place to get the genuine Mason Genie is right here on our official website.
We don't sell on Amazon, in big box stores, or through any resellers.
If you see it somewhere else — it's not us. Cheap knockoffs use weak motors that never pull a true, lasting vacuum. This is the only place to get the real thing.

Great!! Customer service is on point too!
The Masongenie seals well, is easy to use, and keeps foods fresh for longer! I’m even able to assemble salads for a whole week of lunches and they stayed fresh! Game changer!
We use the Mason Genie every day. It is so much easier to store dry and cold foods that we've bought in bulk. It helps the food to remain fresher much longer. This is a nicely designed product and the battery lasts for a lot of charges before running low.
Using the MasonGenie to store some of my homegrown okra until I have more to freeze. So easy to use - I love it!
Filled 6 mason jars last night, the genie was easy to use. The big test will be in a few days when I check the foods for freshness. I packed fresh greens and other veg.
The Mason Genie has lived up to my expectations. It worked right out of the box as advertised. I've used it to seal fermented vegetables for refrigerator storage and to preserve fresh vegetables for nightly salads. I've resealed items with both the lids that arrived in the kit and with lids that I already had on hand. It has sealed and resealed without fail thus far. It has really been helpful in salad prep after a day's work. By cutting and preparing the vegetables for the salad ahead of time, we save valuable time building our evening salad. I've been so pleased with the Mason Genie that I purchased a second kit for a friend.
Very easy to use. You can barely hear it. Looking forward to continual use.
I’m very happy with it, I love how it keeps lettuce crisp!! I hated throwing away salads!
I love masongenie. The cantaloupe was purchased last week and it is still fresh !!
