1. It's nice, but far from perfect bottle.
2. When you clean it or simply refill it with water, my advice to you is to turn it upside down just to make surethat water on the surface is gone. It ALWAYS Leaks When You Reopen it.
3. I keep it in my bag, where I have all different kind of stuff. And I do not like the idea of drinking using the bite valves, after it which in contact with other things (Which Might Be not clean). The bite valve is not covered in any way.
So, I do not like drinking from the bottle, When I have to open the bite valves with my hand after, eg a ride in a public transport.
Summing up, I'm giving this bottle 2 out of 5 stars. This is my experience with this paricular bottle, I also own Camelbak Big Chill Which is a very nice bottle. I would not recommend this bottle to anyone, who considers the purchase. It's better to look for other options on the market.
Best,
Anton
