I have no idea what sous vide is or how it works so these clips were not bought for that. I took them because I need clips for use in the kitchen for various reasons. I thought the price was good for the amount you get so I can use them all around the kitchen. I've read other reviews (I always read reviews before I buy anything) and so far I don't see any issues with my set. While they appear cheaper than some of the other clips we've used (which broke and had to be replaced), they don't look like they'll fall apart in your hands or trying to use them. It's thick plastic and doesn't seem to break, so we'll see. My ends don't fall off and they don't need to be reinserted. They hold up to everything I've used them for. At the moment they have been used to close bags that have been left open and need to be closed, to hold together recipes I've printed out for my family to help cook for the week, to a note on my husband's lunch bag attach it so he can see it the morning before work and attach the bag to the pan so it doesn't float away. They worked for everything I tried using them with. I had no problems and am happy with the performance. If anything changes I will come back and update the review.
