Yep.
Mine has saved the day on MANY occassions....especially hurricane related power outages.
After dealing with enough freezer burned meat, I decided that pressure canning was the way to go.
For me it also frees up freezer space for other items that most people don’t think of freezing and you can’t can, such as nuts, spices, brown rice, and other grains, and some veggies that freeze better than they can, which IMO, is most of them.
