Where is quality control?
We received these Thursday or Friday night and by Sunday one has a hole. After looking at the way it's sewn I can see why. It's only one Seam.  Not a double seam, not capped off with a serger.. a single Seam throughout. One Seam pop and your ball is coming apart.  I went to remove the vibrating piece to sew the first hole closed and ran into more problems. The interior "sock" pocket is not connected within or across to the other side of the ball inside.  This makes it just twist and twist and I still haven't been able to untangle it to remove the vibrating mechanism. Also there are holes ripping at the side of this pocket where it meets the zipper.  This is ridiculous especially after 3 days.  My twins are 9, and mostly lay on these and play their tablets. They are not rough on these items at all and even if they were the product should be made to handle more "play" than this.  We really liked these and have enjoyed them for the few days it didn't tear up. I'm very disappointed in the seams and quality of how this is put together.
