This is such a great tool to incorporate in saving my food and keeping it fresh! I have always been so bad about trying to keep leftovers, produce fresh, and then things expire or go bad. I have seen such a huge difference now with using this set. The pump is so small and really easy to store in my small kitchen. The pump does a great job of taking out the air in the containers, bags and wine sealer in this collection. The battery is rechargeable which is nice and has a good charge on it. It also is pretty quiet when using, and you don’t have to hold it down, just press the button and it does the rest. This is something everyone needs to get and incorporate in their daily food prep and saving.
