NalgeneEasy Sipper - Designed specifically for your NALGENE 32 Oz wide mouth bottle

I got shafted by the seller, who changed the terms of the sale, so what would have been an OK item, turned into a very expensive piece of plastic and cost's nearly as much as the Nalgene bottle that it fits.Save your money and drink carefully.

I bought this addition for my nalgene bottle mainly because during my research a few people complained that it was difficult to drink from the mouth of the bottle without spilling the contents down your chin. Well this device definitely stops that and fits the bottle perfectly. However, since receiving the bottle I've not experienced any problems without using the easy sipper, but now I've bought it I use it because it wasn't cheap to buy.

Good quality item made to fit perfectly into the Nalgene wide mouthed bottles. I often drink directly from my bottles and I've found it quite an awkward thing to do, which is why I bought this accessory. You simply push it into place and when you screw your lid onto the bottle it is pushed into the perfect position and ready to use. My main gripe is I think that Nalgene should really supply these WITH the wide mouthed bottle and not as an expensive accessory!

A Must have with these wide-mouth bottles. As other reviews had said, should be a thing included with the bottle, or at a lower cost.Fits easy into the mouth of the bottle and fits quite snug, however it does not permanently attach to the bottle, its just sits (quite securely though) in place. Personally i put this in upside down as it find water doesnt drip out to the side as much. Also a tip to people buying this, when drinking or pouring out, the water tends to 'glug', so i drilled a small air hole at the top to allow air to pass through, works a whole lot better now, and i have noticed some aftermarket sippers have this hole also.

Although this was yellow- it was more translucent than opaque. The plastic also felt thinner than another one these I got in red. It's possible it was anomaly but if you are buying this for its function/ color I would be aware of those factors.
