I bought some Camelbak Better bottles for drinking out of at home, and some of these Performance bottles for taking in the car. It sits in my cupholder and the water somehow gets sucked up into the top and leaks out. I come back to a big puddle in my cupholder and a wet bottle to throw in my napsack. Not good. Also, because this twists to open, instead of fliping like the Better bottle, my three year olds are not coordinated enough to open it on their own. When I started carrying the better bottle in the car I didn't have the hassle of reaing around to open it for them.

This is my favorite water bottle. I like that I can take it on shorter trail runs and not have to take my eyes off of the trail when I want a drink. I can fill it with ice (using regular ice cubes from the freezer). I've never tried to freeze it, but considering that drinks freeze from the top of the liquid down, so unless you freeze the entire amount of liquid in the bottle, it should still be fine.

It blasts the perfect amount of drink into my mouth with a gentle draw and squeeze on the bottle. I couldn't be happier with this bottle.

The only thing that I don't like, is that someone at CamelBak told me in an email that they're discontinuing this bottle. It was in response to their selling the bottle with a bottle strap for use while running. They said that the strap and bottle combo will change to using the CamelBak Podium bottle, so hopefully the person from CamelBak just meant that the Performance bottle will only not be sold with the strap anymore, but will hopefully still be made and sold. If it's going to be discontinued, I'm going to buy several more.

It has served its purpose well for cycling. I'll put my energy drinks in this while my hydration pack is used for water. The bottle has been very durable, easy to use when on the go and I always love it when there is a spot to clip a carabiner. When I'm not on my bike I use the better bottle for workouts.

I'm not a very big fan of this bottle. Because of the straw, it is impossible to add a decent amount of ice. You also can't freeze it either. Maybe it is good for bike rides, but that is about it.

This bottle rules. It has the bite valve and straw to make it an adult sippy-cup. The polypro bottle is soft as well so you can wrench on it for a faster drink to get back to breathing when you're exercising.

The common complaint can be fixed with a little adjustment. temperature change, elevation change or carbonation will cause it to build up pressure inside and slowly force the liquid out of the bite valve (air bubble on top grows, forces liquid up straw...). remove the straw and it will never happen

If you run it through the dishwasher, clean any dishwasher debris out from under the silicone umbrella valve on the inside of the cap.
