Portable 400ML Electric Self-Stirring Glass Coffee Mug, Ideal for Travel and Everyday Use. Semi-Automatic, Dry Battery Powered (AAA, 2 Batteries Not Included). Perfect for Dining, Gyms, Parks, and School.

Fantastic and very useful! I use it to make cappuccinos or instant coffee, my daughter uses it to mix cocoa well.
It came perfectly packaged and protected, I opened it and saw that it needed two batteries, I put them in, washed the glass cup well, and immediately made myself a cup of instant coffee, which mixed very well.
I don't know if the cup can be put in the microwave, I don't dare to try, I prefer to heat the milk separately and pour it into the already hot cup.
Recommended!

super, Worth Buying, Good Quality, brilliant, super, Good ,you can tell I really like this mug and it's a great size and very nice looking too. very pleased.

Innovative glass; its feature is the built-in mini mixer, it works by introducing 2 AAA batteries, excellent value for money: resistant, practical and easy to clean. The button activates the mixer allowing you to stir drinks in an instant, without using spoons or shaking the contents vigorously.
It arrived well packaged and in good working order!
I was satisfied and I recommend it to the
lovers of practicality and collectors.
