Review on Owala Insulated Stainless Steel Locking 24 Ounce by Tammy Cooley

I've been using this bottle for about a month now. For some strange reason, a strange pressure builds up inside this bottle. So when you open them to take a sip, the water spits at you. Then it's really hard to take a sip of water. Tried to remove the plastic valve under the cover does not help. Also, I don't think the water is MUCH colder than an old plain tritan bottle. It might help a little, but not really. I like the color, but maybe I'll use a different lid next time.
