This product is a great value and works well. Half the price of similar product available locally. Quiet when in operation, unlike my food saver vacuum sealer, which is quite loud. Will order proper bags for unit shortly and will save about 50 percent on cost of packaging compared to other product. The chamber size of 10 x 12 is good for most things that I do. If it continues to work this well in the future, I made a great purchase.Would have given a 5 star rating if not for the manual delivered with machine. May sound a little picky but the instructions are very hard to follow, Found a video on you tube that I used to guide during setup. Filling vacuum pump, etc.. That made it easier to get started.
