I use this mixer to make my protein shakes for lunch. I absolutely LOVE it. Aside from it being super cute, it blends my shakes better and with fewer clumps than the regular shaker type cups I used to use. I can just put in the liquid and powder and press the button and walk away. I love that I don’t have to stand there shaking my cup anymore. And it’s super easy to clean, unlike my full size blender. It is rechargeable and portable, so I can even take it camping with me. For me, using it 2 times daily (once to make my shake and once with soap and water to clean it) the battery lasts about 2 and a half weeks before I need to recharge. The base has lights that indicate the battery level (and they look really cool while you are mixing your shake). The charger is magnetic so it’s really easy to plug in, but other chargers wouldn’t be compatible, so be sure not to lose the one that comes with it. No complaints for me other than you can’t add ice. I like my shakes to be really cold, so I used to add ice. The paddle that mixes is plastic and not very sturdy looking, so I wouldn’t add ice in this mixer cup. I just make my shake early now and keep it in the fridge until I’m ready to drink it, so it is nice and cold.
