I love this bottle. I would have given 5 stars, but it has one problem that really bothers me. The SOUND it makes while you drink out of it. It makes a loud whistling noise that drives me (and everyone in my family that has to hear it) crazy. I’ve taken it apart and put back together. Nothing is fixing it. The bottle is great, matte finish that is scratch resistant, light weight, and doesn’t sweat when filled with ice. If it weren’t for the sound it would be a 5 star purchase for sure.
