I literally use mine every day to turn everything i drink into a frozen variation of whatever I would have drank otherwise. Morning time? Coffee, protein powder, milk, and ice. About to hit the gym? Pre-workout slushie. Trying to get all my macros in for the day? Blended whey isolate protein, fruit, and veggies. The only difficulty is cleaning the base thoroughly as it can't be wet outside of area where it actually blends. Also, make sure you remove the top silicone segment around the mouthpiece to clean as it gets funky in and around there.
