Leak Again?!

I am so done with this brand.  I wonder do they have quality control over the product before placing it in the market.

I brought 4 boxes of this Jingle Jungle Breastmilk Storage Bags and each box consists of 25 bags.

1st box : 2 bags having leakage problem.
2nd box : 5 bags having leakage problem.  In the above photo are the 5th bags.  Sigh.  I still have 11 bags to go.

I am not sure what is the quality like for the 3rd & the 4th box.

I am so mad right now. Argggggggghhhhhhhhhhhhhhhhhhhhhh..................
