I've owned the Bobble for years and purchased it at Target. It's such a cute bottle and cute design but I don't believe that it's worth the money. The bottle is made from thin plastic, is not dishwasher safe (which is a biggie for me) and mine ended up getting warped in shape from the sun when I left it in my car one day. Another downside is that it doesn't fit in the average cup holder, making it impossible to hold upright and handy when you're on the go! The spout is also a poor design where the water doesn't flow very well and is slow to pour out. My last complaint is the high pricing. The filters are so expensive! You could basically buy a brand new Bobble for the cost of a replacement filter which is ridiculous to me and one of the top reasons why I quit using this and tossed it in the trash. Maybe not the same cost now, but they were several years ago when I first purchased this. Now, they run about $6-$7 per filter but most places sell it in a pack of 2 between $13-$16 which is about what the bottle costs and you have to switch it out pretty frequently. All in all, the Bobble is a great concept saving you from purchasing prepackaged water, but the cost makes you want to just purchase the packs of water saving you money instead of the environment, as bad as that may sound.
