They are cheaply made. Not good quality. Not all of them in the pack worked either I packed everything in them to put in the car in the evening, and when I came back in the morning 2 bags had expanded and let air in. The valve is unreliable too. The bags that expanded i tried with a second time after carefully unsealing and resealing them and the same thing happened.
They get the job done. I've never used any alternative brands so maybe this is as good as you get but they aren't great. I wouldn't trust them for any long term storage/
