It’s possessed
Color: Coral Pink
My kitchen theme is pink and this was a perfect addition! Until it wasn’t! Fully charged it, and placed it in its holder ready for use the next morning. From my living room I heard a noise but of course blamed it on Rita (my cat). The next morning I go to make my coffee and the device is knocked over on the counter and of course.. poor Rita! The device worked fine, didn’t send my coffee into a tornado like some do, rinsed and placed in holder. Relaxing and enjoying my morning coffee and all of a sudden this noise happens again and I see the device is on and actively spinning in the holder!!! What the energy? I run to turn it off but it stopped before I can get there. Ok, let’s not panic. Next morning? Device is dead. So I recharge, and lay it on the counter buttons up. Later that night minding my own business, the device is now rattling across the counter!!! Ran over to it, pushed the buttons and it won’t stop! After about 45 seconds it stopped. I recharge again because it died, and the sad thing is still asystolic.. (no pulse), dead, gone. What the??? So I don’t know what to tell you! It looks pretty!
Updated: The company reached out to me and I received a replacement within 2-3 weeks. The new one is not possessed or dancing across the counter. Good power, 3 speeds, 2 attachments (which I seem to use without the power - such as mixing spices). Thank you for standing behind your product in a volatile economic time.

Best frother!
Color: Ultra Violet, Color: Ultra Violet
Amazing customer service! I purchased this frother earlier this year and started using it for my morning coffee. It was amazing and froth up my creamer in no time. All three settings have their own amount of power. So I was very impressed with the speed. The froth texture is heavenly. After using the frother it is very easy to rinse the piece you used. I just rinse it and place it back in its stand. I think it’s very well worth its money. Unfortunately after 4 months the machine would not charge properly so I reached out to the company and within 24 hours, they replied and sent me a replacement. I didn’t pay much attention to the fact it had a 2 yr warranty! So grateful! Thank you so much for your help!

Powerful frother and g4ea
Color: Vivid Red
I love this frother, I bought one for myself and 2 others as gifts! It is super powerful, just the first speed is usually what I use for a cup of tea or coffee, the faster speeds work great for frother hot cocoa when I make a couple cups worth on the stove top. My frother attachment did crack at the top several months after purchase but the company immediately sent me a replacement piece which has been going strong for over a month now. Great handheld frother and company that stands by their products!

First one failed quickly, warranty replacement working great
Color: Turquoise Green
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!
