I've had my Foodsaver for about a month and used it twenty or thirty times. It's amazingly easy to use and works great.
The only problem is that on the "Dry" food setting it doesn't seal the bag well enough to hold the vacuum, regardless of what kind of food is in it. But "Dry" is the default setting, so you have to remember to press the "Moist" button before every seal on every bag. It adds an unnecessary step to an otherwise flawless process.
I don't understand why they even have those two settings. The only difference is in the amount of time heat is applied to seal the bag, and it seems like you'd always want the best seal you can get. If "Moist" were the default setting--or if "Dry" weren't even an option--I'd have given this product five stars enthusiastically. Even so, it's the best kitchen appliance I've come across in many years, and I don't see how I managed so long without it.
