I have never tried or used sous vide bags before but I heard so much about it. So I had to try. It works just like it says and the seal is very tight. I am not sure how many usages it will endure before the bag fails. But for now, I am using it as a food storage in my freezer. I like how the bag are resuable that is definitely a plus. It will help the environment with less plastic waste. In a couple of days, I will use this sous vide bag to cook a whole chicken and see how it will taste. Like I said, I am new to this sous vide bag cooking. That is why I am giving three stars. It is good bags. #rankboosterreview #sponsored #acrato
