I don't know the model I have, but it's a FoodSaver and I got it at BJs probably 8 or 9 years ago. The sealer still works great, but I think the quality of the FoodSaver bags has declined in the last few years. I used to get 4 or 5 uses out a bag (washing between each, of course), but then I bought some that seemed a little thinner and started having all kinds of troubles. I switched to the "Commercial Bargains" brand (from Amazon) and found that they work just as well, if not better than the old FoodSaver bags, and they're about 1/2 to 1/3 the cost (so even if I only get 1-2 uses, I don't feel as bad tossing them).
