Leak like crazy!
I bought 4 of these bottles. The promise of being able to clean them easily was the big draw. After washing 3 in the dishwasher (as prescribed) the never sealed on the bottom again. No matter how I tried to screw them on... they leak like crazy! 3 out of 4 -and the 4th one doesn't leak because I have never unscrewed the bottom. Save your money...
