Easy to use solution for no plastic vacuum sealing
Worked great out of the box. Had a bunch of different sized mason jars sitting around the house, and they work great with the included jar lids. Got it yesterday, and already used it 10 times without charging it right out of the box. This is a great, healthier, glass alternative to ziplocs and Tupperware. It even actually worked on an open jar of tomato sauce. In about 20 seconds the seal button went down, and seems to be maintaining its vacuum.

Use good jars and lids!
This little jar sealer is a game-changer! I was initially skeptical after reading a few negative reviews about it not working, and my first attempt did fail. But I quickly realized I was using an old jar with its original lid.Once I switched to the proper jars and lids, it was smooth sailing. I had just made a big batch of fresh-squeezed juices and filled 12 Ball Mason jars. To my surprise, the sealer worked flawlessly right out of the box, even though I’d forgotten to charge it! It had approximately 22% battery and sealed all 12 jars in no time. The vacuum seal was strong and secure, giving me confidence that my juices will stay fresh for longer.I love how compact and easy to use this sealer is. It’s perfect for preserving juices, sauces, and other goodies. Plus, the fact that it worked even with a low battery is a huge bonus. If you’re looking for a reliable and convenient way to seal your jars, I highly recommend giving this one a try. Just make sure to use good jars and lids, I recommend Ball Mason jars.

Is ‘game changer’ too cliché?
I saw this and thought it sounded like a good idea, so I tried it and now I’m convinced. What an inspired and common sense solution to food storage. The seal is complete and completed in seconds—it even re-seals just as tightly. The quality and durability feel excellent. Very happy with this purchase. Highly recommend. Works great for leftovers and home made salad dressings.

Love this thing
I got this because I have a medical issue (MCAS) with eating leftovers, because of histamine build up that happens with cooked foods. This makes my life so much easier. I can open and re-seal a jar multiple times without concern of food going bad before I get a chance to eat it. The charge lasts a long time. It works so well that at times its hard to get it off the jar. If you have any issues with grip strength in your hands it might be hard to use. I love the fact that it works on both size Jar lids. The pieces wash up easily after use.

Good sealing.
After reading reviews on other vacuum sealers for jars I was apprehensive on trying one of these. I was expecting it not to work as advertised. I am really happy with this unit. Works great ever time.

not quite the best
this is a nice idea, however it does not always seal the jars.  and yes i tried all the suggestions given. after 5-6 tries i gave up on a couple jars. the other 3 took multiple tries to get the seal and I was only doing 6 jars. Â
