Review on 🥤 Eco To Go Clear Double Wall Cold Drink Tumbler - 20oz. Capacity by Steve Whited

I bought this glass nine months ago and used it mainly for water at work. I recently used it for orange juice. As you can see in the attached photo of a washed and cleaned glass filled only with water, the inner wall is now pitted and stained from a single use of orange juice. The straw is also colored and cloudy. So where has all that plastic dissolved in orange juice gone? I must have been drinking. There is also a large crack in the outer wall that appeared one day. As far as I know it hasn't been dropped or hit. It still works well, I just wish it was clear in the product description that this plastic cup doesn't take anything sour.
