Review on Upgrade Your Food Preservation with the Vacuum Sealer Machine: Efficient Automatic Saver for Dry & Moist Food, including One Roll sealing Bag! by Hannah Curi

This is my first time using a vacuum machine and I have read the instructions carefully. Press 2 buttons to open the lid, cut the vacuum bag to the right size, press the zipper, put your favorite food inside and seal it. The first thing to notice is that the lid should be closed and you should hear "ka" to confirm it's closed. Second, the side with the lines faces down (the seal is best leaned against a small indentation inside, especially with wet food). Then you will find that the process is very simple and can be completed in a minute. Very good, this way your food will be better preserved.
