Question: I imagine the spout can easily get dirty and pick up germs since it is not protected like other water bottles?
Document: I was looking for something that would fit easily in my son's Britax cup holders. Other water bottles fit, but he couldn't get them out. This one is just the right diameter and works great.
This is a very sturdy water bottle and we like the sippy cup type lid for toddlers who were annoyingly chewing my other type camel backs to pieces. The kids drop these and they don't break. My only complaint is that the rubber piece inside the lid/bottle can come undone and then the water easily comes out the spout. But so far this is our go to bottle for a sippy cup/water bottle for our 1-5 year olds.
My kids love these water bottles. I got a couple different kinds for them and these are the ones they like best. I like that they don't leak, have the hard sipper spout, and just have the valve insert as parts. So easy to wash. I read that some kids have problems with the valve but my 1 and 2 yo have no problems.
My 6 year old and my 2 year old both complained about this cup. "There's no water!" they said. So I tried to drink from it. The amount of suction it takes to get a decent amount of water into your mouth is excessive for an adult. I can't even imagine a kid trying to use it.Really wanted to like it, but have found it completely impractical.
My wife and I have many &#34;no spill&#34; bottles from several brands for our two year old son. They are not very durable. We bought two of these hoping that the durability would be better. The bottles are very well made; however, the valve is very strong. There is no vent hole in the cap, thus requiring pretty strong suction to get water out. Also, there is no straw inside requiring this to be tipped like a normal bottle.
I'm very disappointed with the quality of this Nalgene. I have owned Nalgene bottles since 1998, and this is the first time I have seen one crack at the bottom. Our youngest boy (who is 2) dropped it on our driveway, and the bottle cracked at the bottom. From what I can tell the crack goes along the seam that's at the bottom. I thought these things were practically bullet proof. I'm not sure we're going to spend more money on another bottle like this.
It isn't bad overall. My 3 year old doesn't like it because its to hard to drink out of and prefers the camelback Eddy water bottle. My 1.5 year old likes this one, and I like that he does since unlike the Camelback Eddy it doesn't leak if the nozzle is pressed etc.
I bought this for our granddaughter thinking it was a &#34;water bottle&#34; but it was more like a &#34;sippy&#34; cup. the sipping part is hard with holes, not at straw or retractable or coverable drinking spout. Even though I returned it because I was looking for a more traditional &#34;water bottle&#34; this is a VERY nice sippy-cup bottle with nice, durable construction and beautiful design.
Until last week I would have easily given these a 5-star review. They are attractive, don't leak much and my son has used The Grip-N-Gulp since he was about 1 year old. He has had the same cups for over 2 years with no problems. Now, I just had to buy more since my daughter is starting to use sippies and likes to steal her big brother's.
The tough, durable water bottle you expect from Nalgene in a size my toddler can easily handle. He likes using it and likes the cars on the side. When he turns it upside down and shakes it/bangs it on something we get no more than a couple drops out. So it stays sealed really well.
Answer: yes
