I've been using mine for about 2 months. I mainly use it for freezing meat and poultry but I have also used it to keep my mushrooms fresher for a longer period of time in the fridge. I froze some asparagus using this and it's amazing that they are still so green and no wrinkles! (maybe if they come up with an xxxxxlarge bag, I can put myself in there and forgo the wrinkles!).

Sometimes sucking out the air can be frustrating because for some reason I just don't have it in the 'perfect' spot so that it doesn't suck the air out. When that happens, I look for something small and sweet to eat...savor it while I calm down...and then go back and try again. (it usually works )
