As described, quieter than version with black rubber holder at top
I bought this as my second bottle/backup. I already have a similar model that I purchased a while ago. The bottle I already had was great at keeping stuff cold in 100 + degree F weather. The only issue I had with the the model I had was the top stopper sounded like a dead duck when unscrewed.
Straight out of the box, his product model has no black carabiner attachment at the top. The stopper is a lot quieterโ no loud duck noises when you go to unscrew and take a sip.
This product actually breaks down into three main pieces. The base of the tumbler screws apart halfway down at the widest spot, so itโs very easy to clean. This product works great for making fine powder-based drinks (matcha, collagen, etc). Great buy!
Iโll update this review when I have more to add after using it!
