I love this milk frother, a must have for coffee lovers!
Color: Silver
I absolutely love this Bonsenkitchen milk frother! It creates the perfect foam in seconds and my coffee has never tasted so good. The rechargeable feature is so convenient and I love that it comes with a stand to keep it organized on my counter. It is easy to use, easy to clean and works perfectly every single time. If you love coffee at home this frother is a game changer, it makes you feel like you are at a coffee shop without spending a fortune. Highly recommend!

Does the job!
Color: Silver
Great frother. Love that it's rechargeable. 3 speeds, double frothing ring. This one is way better than my last, battery operated one. A lot of people giving are negative reviews or deductin stars because they think you have to cycle through the speeds to turn it off - they're wrong. You just hold the button for a couple of seconds and it turns off. Highly recommend!

Stand was my favorite part, hated how close off and higher speed is
Color: Silver
Well the first lesson is dont hit the power button to turn off, as it goes to 2nd speed and slings your drink everywhere. Im not happy with the stability of the brother, had better, as free with coffees. Positive is, it has a stand, it does have 3 speeds, just never needed the other two speeds, and if you dont hold power button long enough to turn off, it goes into higher speed.

I drink a specialty coffee that uses a Keurig to dispense it when it comes out pot and it mixes well I use this to mix my collagen, my coffee and some mushrooms to help keep me active and it works perfectly. I’d recommend this to anybody that is mixing their coffee with others things.
