I have that one from Costco but bought it at Sam's. I have probably run about 50 bags through it since December. It does great on dry foods, but doesn't get a terrific seal with anything that has a little liquid like the pulled beef or pulled pork that I sealed today from my leftovers from the party on Saturday. I have been using pint, quart, and gallon bags. Have used the marinade function and was pleased with it. Also, have used the resealable bag and liked that feature too. I am happy so far for the $120 that I spent. The next one will probably be a LEM.
