Dr. Anna's Shaker Cup, 26oz Eiwitshaker

Dropped it on concrete once and not a single dent, plus it never holds onto that old shake smell even after sitting in my gym bag all day. The stainless interior is a huge upgrade over my old plastic one.

The stainless steel interior doesn't hold onto the smell of my vanilla shakes at all, which was my main issue with the plastic one I had before. It's also survived the dishwasher a dozen times without the paint chipping.

Dropped this on my tile floor twice already and not a single dent, which says a lot given how clumsy I am. The stainless steel doesn't hold onto that old protein smell either, unlike the plastic one I used for years. Dishwasher safe is the real win though.
