i have a 3 year old and a 2 year old and they've been using this bottle for the last year. it's the only spill-proof bottle i've been able to find. no trouble with the bite valves and i love that it's bpa-free now. we just bought new ones because of the bpa and because one of the bite valves was starting to split a little. not bad for using it every day for more than a year.

My wife has the larger sized one and the kids kept stealing it. They are 5, 4, and 2 and do not have any problems with the bite valve. The widget factor seems to encourage them to drink so I love em. Disassembles into 4 parts (bottle, cap, straw, bite valve) and is fairly easy to clean.

I bought this bottle for my active 4-year-old to bring along to his various sports classes, its the perfect size as 0.5 liter is significantly larger than his kiddy sippy cups thus ensuring that he will not run out. It's easy for him to use and the bite valve prevents spillage or leakage. The bottle fits nicely into his school backpack, 0.5l should be sufficient when he starts full-day school this fall. As not many kids use Camelbak my son can easily identify his bottle and is proud of his "adult" bottle. So far the bottle has survived his rough handling, the snap open valve is a cinch even for his little hands. I would recommend this bottle.

I love my bottle so much I purchased the .5L bottle for my 7 year old. He would rather drink water from this bottle than a cup when we are at home! It's the perfect size and fun for him to use.

love it for working out or keeping it in the car so i drink more water when i'm out and about. perfecto.

Great bottle. I miss it dearly. It was beautiful! It clipped to my pack and fit so nicely in my 4x4 cup holders it didnt leak (sigh!) If I ever find the s%#tbag who took it, I'll make sure he stays hydrated with the fishes permanent like see!!!

I really like this bottle. You don't have to tip it up to drink from it, and the bite valve is kinda fun to bite on. It's super easy to drink and I find myself doing so much more often. The ONLY negative is that it's a little too fat to hold in my hand while running comfortably, so I need a different bottle for running. Oh well.

I bought this bottle for my 5 year old and it is perfect. She loves carrying it around and it is super easy for her to drink from. It is holding up very well to being dropped and the bite valve is surviving my active chewer!

love it. fits in the cup holder in the car. easy to carry. bite valve is great, easy to get plenty of water from w/out a whole lotta work. no spill. all 5 family members have one. no more throw away water bottles. recommend this highly.

I bought this bottle in a .75 and .5 size. I find that I drink more water when I have this bottle around and I like that it fits in cup holders. The only down fall is that it only took one drop (.5) and the little snap on the straw broke only after 2 weeks so I will be returning it. I didn't buy the 32 oz size because I figured it would not fit in cup holders but after taking the .75 on a recent backpacking trip I will need to get one as the .75 was not enough water. I am not a fan of the big spout on nalgene bottles (I always make a mess) so this was perfect for me!

Bought this for my wife and she's crazy about it...takes it with her everywhere. Sturdy, reliable, fits any cupholder, and of course, BPA-free.

I have this water bottle in the 32 oz size and have no complaints. This size is great to fit in my cup holder. Color choices are good. It is great that you can purchase replacement parts, if every needed.

I love this water bottle! It totally makes me drink more water because of the bite valve. It washes nicely on the top rack of the dishwasher and does not contain any of that bad plastic...loved it so much I ordered two more for myself and two for a friend!

This bottle is, in itself, not a bad choice. Well designed and proportioned, it will hold up nicely. However, the sizing was an issue for me. Half a liter was just too small. I know, there's other versions, and I have those other versions, but I think it's worth noting. The other thing would be that the valve can get pretty nasty. If it gets left along for very long, stuff can start growing in there or anything like that. Because of the way it's compartmentalized, liquid gets trapped right at the top, and stays there until drained. Just keep this all in mind. As a water bottle though, it functions quite well, and looks great.
