I own two pair of these podium ice bottles. Prior to these I owned polar bottles. The ice bottles do keep items cooler a little longer than the polar bottles. Probably not enough to warrant the premium price. The lids on the polar bottles are the old style pull outs. What I found with those is that the moving part would become loose, so you open the bottle with your teeth and it would slide back shut. So I would throw away bottles because of the lids. I like this spout better. I think it has lasted longer. So when you add the little bit cooler, the better lid and the longevity, I think that they are worth the money. They are top rack dishwasher safe.
My complaint? Out of the box they are slicker than snot. You won't notice it until you get out on the road and you try and pull them from a cage with a sweaty hand. I sent a letter to CamelBak and got a nice canned response back. So I created my own solution. Take a little sand paper to the top 1/5th of the bottle. Don't go crazy, you are just looking to rough up the surface a little bit. You will be happy you did, or curse the fact you didn't when you have to turn around to get the water bottle you just dropped.
One other tip. When your water bottles start getting "the funk", let them soak over night with a denture tablet. Then run it through the dishwasher.
