While it has the Cabela's name on it, it looks very similar to my Weston Pro series.
If it is, it will last a long long time. I process about 25+ bags a week, even more in the summer. I've used mine for 3 years with NO problems.
If using it to seal chili, stew or soups just chill the food in the bag for a few hours and then seal having no mess or leakage.
