Have used the Pro-2300 constantly for the past six months, and have had NO problems at all. The previous reviewer described liquid in the vac vent and tray. You CANNOT vac seal wet items. You have to FREEZE first and then seal. This is clearly stated in any vac sealer literature. Just put the stuff in a vac bag, stand it in a box in the freezer, like a cereal box, and then seal when frozen. We have found that you can partially freeze meat, and then seal with very good results. For freezing raw, it does suction up some blood/juice, but you have a manual seal button to stop the suction and seal the bag.You just have to pay attention and be quick! NEVER let the suction pull liquid from the food into the machine. That is not machine error. That is operator error. We freeze a lot of things! It it large, and has a permanent place on the counter! Great for resealing chip bags, too! We keep a box of gloves, a sharpie marker and the vac bags in the cabinet drawer directly under the sealer. We are ALWAYS prepared for packaging!
