Review on Kootek Vacuum Sealer Bags, 6 Pack - 3 Rolls 8"x16.4' & 3 Rolls 11"x16.4' Food Saver Bags - Compatible with FoodSaver, Food Vac Bags Roll for Storage, Meal Prep, Sous Vide by Laura Russell

These reels are practically useless. They are twisted unevenly, which leads to wrinkles in the plastic. Therefore, the vacuum sealer cannot completely pump out all the air. As a result, the machine never reaches full vacuum and automatically seals the bag. If you seal the bag by hand, just note that the vacuum isn't full, which basically kills the whole concept of vacuum sealing. Do not buy. Stick to Foodsaver Buns. They are of high quality and that counts.
