Query: Disappointing...

I received these bags as a gift while my baby was in the NICU. I have never had a problem with them leaking while thawing milk... most of the time the bags wouldn't get to the freezer. Several days ago, at 2 AM, I was transferring milk from the bottles I use to pump into bags. Before I had even zipped the bags shut, there was a puddle of milk on my counter! By the time I managed to get the milk into another bag, I lost more than an ounce!I'm glad that I did not waste my money on this product, and certainly will not be purchasing it myself.
