I love this mixer
Size: Basic Frother, Color: Black
I love this mixer. I don't know how we got along before we had this. We have had this small hand mixer for 2 years, using it several times every day, day after day and it finally stopped working and I am ordering another one right now. I can't live without it. I make our bullet coffee with it. My wife makes her morning shake with it. I could go on and on but I need to get another one ordered right now.

Works perfectly!
Size: Basic Frother, Color: Silver
The first unit I got, the charging LED was not working so I don't know if the unit is charged. I returned the unit back to Amazon and got a brand new unit the next day. Great job, Amazon! The 2nd unit has been perform perfectly. I use it to whisk eggs in the morning to make French toasts, waffles, pancakes. All comes out perfect! Also, the mike froth for my morning latte and cappuccino. Don't under estimate this small unit, the spin is fast for high!!!
I saw some negative review on the durability of the unit. I hope this is not the case. I'll update if anything changes. As for now, highly recommended!!!

Mixes my protein shake powder
Color: Blue
My husband and I both drink protein shakes daily. We have vortex mixers that work great, but they are plastic and getting old, and really needed to be replaced.
In an effort to reduce microplastics in our lives, I am trying to use less plastic mixing cups. I couldn't find anything small enough (other than regular blenders) with glass and metal parts that would work well for us.
During my search on here, several frothers showed up. This one caught my eye because of the amount of sales, quick delivery, and of course, decent pricing. Some of the reviews had me a little skeptical, and time will tell regarding the longevity, but so far I am pleased.
My protein powders are on the heavy side, but this little frother really gets the job done. Instead of having to use separate mixing cups (saving me on dishwashing), I just use my morning coffee cup (it's big enough) to mix my protein shake in. My husband just uses a regular glass.
Neither of us can believe the power this little thing has. We are getting smooth shakes!
Here is what I really like about it: It is powerful and mixes well; the frother is metal and not plastic; it cleans extremely easy; after making several shakes the battery has not died; can be used in glasses, coffee cups, even disposable cups (when we buy donut shop coffee); and I love the little stand which takes up barely any counter space. Less plastic, less clean-up, dependable (so far), and small, making it convenient even for travel.
I'm really glad I got this, and hope it will last. One last thing, do not turn it on while cleaning under running water. (Yes, you can laugh.)

Powerful frother with a long rechargeable battery life
Color: Black
After purchasing three of the battery operated frothers. I finally found this amazing frother. It is very powerful so you do have to be careful not to slosh liquid out of your cup when you’re using it. But I have found it helps if you rotate the frother in a stirring motion while you are using it. That really helps keep the liquid from overflowing out of the cup. It has a sleek design and is rechargeable and the charge less about two weeks.I love this one so much. I take it with me when I travel. I actually left my original one at my mother’s house the last time I visited her and have ordered another one for my house. Highly recommend.
