Slight disappointed when I received this bottle. I have now used it a few times. I love the flip spout!! Nice not to get a mouth full of grit. I try to position it in the cage so the button doesn't hit anything and flip the drinking spout up. The 2 star rating is for the failed attempt at an "insulated" bottle. It is only double walked. There is NO insulating at all. At least not like the Camel bak I also use. Insulate the bottle and it would get 5 stars
