I have been using this Mug for last 2 months. The magnetic capsule is a miracle I will say. It stays stuck the base as it's really strong but stirs the liquid very well. Especially any drink which settles while drinking. It's as simple as pressing the button and it start fresh stir and you don't have to open the lid. I will highly recommend this Mug.
It arrived in few days. Quality is good and it works well. I wish I knew this mug when my kids were young as it would have saved me lot of work. Never the less, lots of chinese wordings but it also has english instructions. It's very easy to use and I will suggest go ahead and buy yours.
