“You have had how many iterations of this product now and you still haven't added the most obviously useful feature, a marker (that is not basically invisible) for where 600 ml is. I have used tape or a marker on my shakers to be able to fill the right amount of waters without squinting on the bottle as I hold it up to my face next to the window.
I really don't understand how you have not fixed this. Makes me think that no-one in your company actually use your own products.”
“I like this new cap, especially useful when I prepare the shake in the morning and eat it for lunch: just a rapid shake and it's all well mixed again.”
