I just bought this one last week, it is the high end model and I highly recommend it....we buy bulk meat and poultry etc and vac seal it then freeze it....meats etc keep for up to 3 years frozen....you can also vac seal so many other things in it. I have a friend that has the same model and been using it heavily for years with no problems, he has cows and slaughters then vac seals it all.
The bags are much cheaper on ebay and do the same job
