I have an old BlenderBottle for many years, maybe seven plus years. I use it for drinking protein. One of the things I realized when I washed it in my dishwasher this week, alongside other beakers, is that most of them had residual water even after the ‘Heated Dry’ mode. Water still remains after washing and drying, especially on the non-steel items. But there was one exception - BlenderBottle was the only one that, even when upside down, did not have any liquid. I was wondering why and that’s when I noticed these tiny holes that were made in the lower rim of the bottle. I think they’re specifically for this purpose so that when you wash it upside-down in the dishwasher, water does not get collected and seeps through them.

Now that is a really good design!
