I want to start off by saying this is my own opinion. I’m not being reimbursed in any way. I always go to the reviews of people who are posting simply because they truly love (or hate) the product so I feel like I should post this. I truly love this bottle! I struggle to even drink one bottle of water a day and a few friends recommended getting a bottle like this. I love it! It is very sturdy and does not leak. Even after it turned over in my car. It is easy enough to open and close that my 18 month old daughter can do it on her own. The lock has been one of my favorite features so far. I have already recommended this bottle to many of my coworkers and would buy this bottle again. The shipping was extremely fast as well.
