The flow rate is average, but what really sets these apart from other brands is the ease of taking it apart to clean. It goes back together just as easy. I soak all the pieces in water with some bleach. I have done this for about two years and they are holding up really well. I do not have the money to buy new bottles all the time when I see mold lurking in the lid, and I know a lot of people keep them in the freezer to keep them mold-free, but we have limited freezer space.
Love that it holds more than standard tall bottle but is not too unwieldy to actually drink out of, like full 1 liter bottles. Does not leak. Flow rate for valve could be better but not terrible.
