These are our favourite bottles and we have tried several brands. Yes the designs flake off but the quality of the insulation, portability and the great leak proof design makes them worth every cent. Easy to clean with bottle brush, bicarb and vinegar.

I want to like this more because the non spill spout works well but... 1 its a little hard to get in there to clean 2 the mouth of the bottle is small so again hard to get in to clean 3 the lid is not attached so kids will easily lose this 4 the spout design is such that you really need to suck hard to get a bit of water out 5 the double walls mean these bottles are generally heavy.

The bottle and cups are great we have two sets in the car and two medium drink bottle for the kids

The only thing that really bothers me is all the paint is flaking off on the car cups and it has now started on the drink bottles I brought the drink bottles in January for $40 each including post for this price I expect better that than this hey look terrible and crap
The company said bad luck flaking is not covered
I have had cheeky brand drink bottles and sigg none of them have ever peeled
I won't be back to buy any more

My daughter has been using the ecococoon stainless steel drink bottle for over a year without a problem. It keeps her drink totally cold due to the insulation, but we haven't tested with hot drinks as yet. The mouthpiece is excellent quality and truely non spill. We've had to replace them a few times, as my daughter is an extreme chewer, and nibbled the spout. It is very well made and sturdy, and we have never had any issues with leakage. My daughter tends to place it down hard on surfaces which left dents in our wooden furniture, so we purchased the neoprene cuddler for it, and have had no problems since. I love it so much, I've purchased the whole family one each for Christmas. Customer service is excellent, I highly recommend them.
