I'm happy with mine (V3485) and have had it several years now. I don't use it a ton, but between general freezing and sous vide, it probably gets used lightly a couple times a month. Then a few times a year when I do pulled pork and bacon it sees a bit more volume. I buy the rolls and like them much better than the pre-sized bags. Granted, you have to seal both ends, but they are much cheaper. Just yesterday, I threw a half rack of uncooked beef back ribs into one and sealed it up. No issues at all.
