I just threw away 7 ounces of milk because of a leaky bag. Like others have reviewed, two bags just sprang leaks at the seams. One bag had a small hole and the other had multiple holes. I'm very careful with my milk stash. After I threw those 7 ounces away, I almost lost another 4 but noticed the water got a little cloudy when I went to turn the bag over. I'm hoping water didn't seep in but I couldnt afford to throw another 4 ounces away!! Horrible product and now I'm worried about the rest of my freezer stash!
