Review on 🚰 Aquatix 32oz FlipTop Insulated Sport Bottle - Pure Stainless Steel by David Crawford

I appreciate the durability and shape of the bottle. It's nice to have a bottle of this size that fits in gym equipment and cup holders in the car. However, (rubber?) pads are impossible to clean, and I suspect it's impossible to prevent mold from growing beneath the surface unless you douse them with bleach after each use. You can rub and soak as much vinegar, but the mold won't go away. There is no replacement for them either, you have to buy a completely new case, as far as I understand it. It doesn't specify what material these o-rings are made of, but I've never had this issue with any of my other stainless steel o-rings.
