Absolutely loved this for the two months it worked but it completely stopped working after only 2 months. Update: I couldn’t decide on stars. The company honored the warranty and sent me a replacement. So far it is working great and I love it like my first one. Hopefully it will last. If it also fails quickly I’ll update again and take off stars. If it lasts I’ll increase stars because I really do love this. It works far better than any other one I’ve owned, it’s a nice light weight, comfortable to hold, has strong power, holds a charge well, has three speed options, and has a stand. I’ve tried multiple frothers. This one is by far the best one yet with best design and features.

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.
