http://www.dpsnutrition.net/get_item_bn010.htm Paid about $13 total with shipping at DPSNutrition.com, been putting it to good use for a few weeks, and now all of a sudden I'm noticing leakage when I'm blending shit in it. A few drops here and there, nothing too serious, but it's enough to make a mess especially if you're blending bananas along with the milk and powder. And when I'm just carrying water in it on my backpack, water would leak out when I'm out walking somewhere. Does anyone else's bottle leak or is it just mine? Thought this would be an awesome product considering how most other shaker bottles are $3-5 on the market, but I'm deeply disappointed. For what it's worth, the "whisk" ball works pretty well though.
