Negative Positive
Title: Don't know if mine is defective, but....
Review: The bottle I received makes a weird noise when I am drinking from it. The sound gets a chuckle from my husband and my kids each time I use it, but I don't want to risk stares from people outside of my house, so I never take it anywhere with me. Additionally, it gathers a lot of condensation...it kind of needs its own attached coaster to solve this problem, or to be more insulated, but it lacks in both areas. The only thing I really like is the size...I will be replacing this for something more carefully designed.
Is the review positive or negative?
