Query: After 3 returns for defective zippers, I give up!

The first time I purchased this bag, I loved it. Then it lasted less than 6 months. The metal part that keeps the tab for the zipper on broke off. So I returned to skip hop and they finally sent me another one. That one lasted 3 months and the SAME thing happened. Sent that one back and got another one and literally in less than 5 mins...unzipped it, put bottle in, zipped up and it broke off AGAIN. I am done with this product and quite possibly skip hop. This is my first skip hop product and I worry that other product quality may be like this. I wanted to love the product, but the quality of the zipper is horrible.
