Review on Nalgene Easy Sipper - Designed Specifically For Your NALGENE 32 Oz Wide Mouth Bottle by Robert Demissie

The good.and the bad.The good:1) It easily fits inside the neck of the wide-mouth Nalgene bottles and keeps the liquid from sloshing around when trying to drink it on the go.2) It's also easy to wash.The bad:1) It isn't clear in the ad that this is for only ONE cap. Once I received it and realized it was only one I then looked at the title and see that it ends with the word "Black." It should be more clear that this is only for one and not for six, like pictured.2) The Price.this is a $0.05 part, which is why I thought this price was for six of them. But Nalgene seems to be only one making and selling these for the Nalgene bottle so if you want one, you will have to pay.Personally, I can't quite figure out why so many people like the wide-mouth bottles. They are very expensive and unless you want to wear your drink you will need one of these in addition to the bottle. That's something like $15 for a water bottle. I do understand that the wide-mouth bottles are easier to clean but I only put water in my bottles so that feature is lost on me. I also recognize that you can fit ice cubes into the wide-mouth bottles.but I don't like cold water and when I do, I simply fill the bottom inch of my water bottle with water and then freeze it.Prior to a long trip I recently purchased both a new wide-mouth (with this sipper cap) and several of Nalgene's old style white thin-necked blue-capped 32 oz. bottles. The old style bottles won out by a mile. They are much easier to drink from while driving, walking, hiking, etc. than the wide-mouth bottles. They also are made from a softer plastic which I like more. Someone mentioned that there is difference in materials between these two that could have health consequences but 1) most of the super bad crap that used to be in plastic reusable bottles has been banned and 2) I'm not leaving water in these long enough for it to matter.
