O2 Cool Drinking and Misting Bottle

Decent water bottle- my daughter loves the mist/spray feature (and I love that she can cool down quickly during soccer games, etc.). Definitely note that this bottle is not insulated- it gets hot just as quickly as a regular bottle of bottled water from the store does- that was a little disappointing to me. I figured/hoped it would do a little better than those. (I bought an insulated one for my other daughter and it stays cool MUCH longer, as expected). The other down side is that the top of the bottle (the part you unscrew to fill it up) got gunky really quickly- esp the nozzle thing that you pull out to drink. With other, simpler water bottles, you can disassemble them a bit to clean them but this one is all fused together, I assume because of the misting feature, so you really can't get in there to clean it. We've had it for about a month and it does go to camp in a backpack every day, so I'm sure it wouldn't get as gross under different circumstances.
