Bobble aims to make water better and become the Britta of sports/water bottles. A great idea why wait for water to filter then pour into a bottle, just fill and go. It is also BPA free and reusable, how nice.
With it only costing $9.95 for an 18.5oz, what do you have to lose, when normal water cost $2 at WAWA. They say you should replace the filter after 40 gallons thats 640oz 34.59 refills. so at roughly $2 for 24oz that is 26.66 bottles @ $2=$53.00 seems like a savings. Really you can't loose.
