Jaison, they are a very good household appliance. I'll mention also that you do not need to spend this much money to get a very serviceable unit. I have currently been using a very inexpensive Ziploc brand that does a perfectly adequate job and it easily handle the bags that are 11" wide. This new one is 14" wide. I age the whole cryovac packaged rib eyes and strip loins in my fridge for about 45 days at around 40° F to 42° F and then cut them into several awesome steaks, vacuum them, and freeze them. The meat that grocers have already cut into steaks I'm not going age them; I'll either use immediately or immediately vacuum pack and freeze so that they do not freezer burn. Be sure your hands, gloves, knives, cutting boards, work surfaces are uber clean and germ free. When I'm doing thatI keep one sink filled with hot soapy bleach water and the other one has hot water running slowly so that I can quickly sanitize and rinse a cutting board, knife, etc.
Of course you can do that with game that you've taken so that it'll keep much longer without freezer burning, Same thing for fish; dress it, vacuum pack, and freeze it. You can do garden veggies too although some of those do need blanched. Blanching and vacuum packing stuff like that is far less time consuming and much less labor intensive than canning too. And this way it's almost like fresh picked instead of canned.
You can also vacuum pack ammo and stuff like that too.
And yes, Mindy and Huh? What? gave you good advice.
