CamelBak eddy

Summary

Horrible product. I do not recommend for outdoor setting where you might get winded.

The bottle construction is extremely tough and well built, however, the suction is horrible. When trying to suck water through the straw and mouth piece, you really have to work. Tried drinking while running and found that I had to suck so hard it left me light-headed. 

I do not recommend this product for exercise situations, but should work well when you are not winded like driving or casual stroll around the neighborhood. This is probably why I got on clearance at Dick's Sporting Goods.  I suspect this is why they sell a different cap for this product which does not include the straw and functions more like a normal water bottle (i.e. Nalgene).

Summary

Durable enough — but utterly dumb design. You have to hold upright, look down, and generally appear like the Spartans sipping a frappe on the "Meet the Spartans" spoof of "300."

I just don't get this product. If you're going with a water-bottle design, why put in a bite-valve/straw that makes you have to literally look DOWN to use it?

On trails in White Mountains I had it as my "convenience water" and my hiking partner forever saw folks coming up the trail before me on water stops because I was LOOKING DOWN to drink out of the thing. And, at that, I was only drinking after finagling the somewhat overly-firmly-retracted bite-valve open in the first place.

This product is an utter waste of the resources used to make it.  It has the 1.5 star only because it takes a beating ... well, except the straw comes off after the first cold night (30°F).  

I love Camelbak ... but this is like that bad movie they should have never made (oh, and by the way, "Meet the Spartans" is WAY BETTER than "300").
