Absolutely love it. I have started with half gallon and quart size mason jars. I have vacuum sealed, coffee, loose leaf tea, walnuts, crackers, mixed nuts, strawberries (stored in the fridge), beans, and a few other things. I love hearing the sound of air rushing into a jar when it's opened. My MasonGenie is right there on the counter ready to reseal a jar. I need to buy some pint size jars as well. Lots more to be sealed.
