I must have gotten lucky when we got our model as it's been rated very highly by an independent source: http://www.vacuumfoodstorage.org/reviews/foodsaver-v2840
Check out this guy's foodsaver test on keeping lettuce fresh in a mason jar compared to just using ziploc bags. How much produce goes to waste in YOUR frig?
Mason Jar premade Salads (don't forget to vacuum seal them!) Make them up days ahead. http://www.huffingtonpost.com/2014/06/06/mason-jar-salads_n_5452313.html
I also gotta try rinsing salad greens & veggies in vinegar before vacuum seal. Even without the vacuum vinegar will give you a month of storage (from what I'm reading). Put a paper towel in the bottom of the jar first.
Soon I hope to make up some (non-ground) venison jerky and I've had this Foodsaver quick marinator sitting around and never really used it for much. Marinating jerky meat in minutes instead of hours with the same results sounds pretty interesting.
