Not impressed
"I don’t understand the great reviews. I can’t even get a decent drink out of mine properly. I assume it’s because there’s no second air hole to allow it to flow. Huge design flaw. It’s also very heavy for a slim size. I gave 2 stars for the slim design and the handle that is very nice. I really wanted to love it. Maybe I’ll get used to it. I needed something lightweight for carpal tunnel still searching. So far Contigo is still No. 1 in my book as far as spill proof, lightweight and fits in car cup holder."
