Best kitchen device!!
Color: Black, Color: Black
This frother is absolutely amazing such power behind it . Quality is just as amazing made very rugged. And I love the stand and the best thing about it is no more batteries to change now we just charge it up. I HIGHLY RECOMMEND this product to everyone and I will be buying more of these for gifts and more for our winter home also. You won’t be disappointed at all.

Works as described
Color: Black
Love this whisk. I have arthritis and this is light weight enough for me to use. I love the push button, and the stand for it. It’s really easy to clean, and it blends my shakes nicely without leaving the powder behind.

Very Powerful Frother!!
Color: White
I’ve been using a frother daily for my drinks, and this one really impressed me with its power for such a compact size. It blends heavier powders into smooth, clump-free mixtures in seconds.
I’m a big fan of the build—the metal whisk gives it a solid feel, and it comes with a stand to keep it neat on the counter instead of being shoved in a drawer. Cleaning is a breeze, just a quick rinse, and the rechargeable battery lasts much longer than I anticipated between charges.
Just a little tip: start in a taller cup and don’t fill it all the way to the top, as this thing can create a serious vortex if you’re not careful. Overall, it’s been a super handy little tool, and I’m so glad I bought it.

Still The Best Frother Ever!
Color: Black
I love how it is easy to use, how it holds a charge, and how much power it has. I've only charged it once since I got it & I've been using it on a daily basis!!! Though it isn't a long time, I'm happy with it so far! I definitely will recommend it to anyone looking for a great frother. If you are looking for one, look no further! You won't be disappointed! I've read some comments where they found it to be too strong that their drink spilled everywhere. But for me I have not had any incident of spilling over. I have used it both for my coffee and my matcha tea and it worked great without any spilling over. You just have to start with the lowest power and ensure that you have a large enough container to have a room for your frothing. My sister tried to use it recently during her visit to make us matcha tea. However, she experienced spillage all over the cup, because she had used a small cup. Otherwise, she liked it very much and said she will get one when her battery operated one stops working...
Another thing I like about the product was the customer service that I had received. When I got my first order which came quickly, it wasn't working after having charged it over 24 hours. It was not turning on at all. I returned it and ordered a replacement which I received within a day or two. This time after charging it for the recommended amount of time, I was a bit skeptical when I turned it on. However, I was pleasantly surprised that it worked like it was supposed to and it has been working ever since having charged it only once so far. I may come back and give an update depending on how it does after 6 months of use, so keep in tune...
I don't know if there is a way to write a new entry as a follow up to the old entry, so I'm going to add my follow up comment over here.
May 23, 2025 - I love my frother more than I can say in words. It's functionality has not changed a bit from the time I have purchased it. It charge lasts several weeks to few months before I charge it again and the power is still the same. Recently I decided to buy another one for my office use. I like the white color and so tried it but that one wouldn't even turn on. And then I got a gray one to have a different color. That one was much weaker than the black one I own. Then I replaced it with another gray one within few days. I tried it and it was exactly the same as the one I already replaced. So then I decided to go with a black one again hoping that it would be the same as the one I have. The black one did much better than the gray ones in the strength or power of the frother. However, it is weaker than the one I already have been using since last August. While I am not very happy with the quality being inconsistent in all of the ones I have tried including the recent pictures of the black one, I have decided to keep the black one because it is relatively better than the gray ones I tried. What I don't understand is why there is inconsistency in the quality of the same product by the same maker. I am beginning to wonder if the black one I purchased in Augusta last year was anomaly of a quality and a good way. Maybe I lucked out on my older black frother, but I'm unsure if quality is going to get better if I were to order another one. I have a sister who is a pro in making coffee drinks and she was the reason I had ordered this frother to begin with. She uses a battery operated one at this time and I have been thinking about getting her one like mine. While I am still skeptical, I am going to give it a shot and order her one sometime soon. If it doesn't work, I guess we will return it back. But one thing that I am grateful is that I have been able to return every one of those that I have tried recently with no issues. I hope that I don't have to return my most recent purchase in black. I was not even able to review the new purchase because of the item being the same color which is crazy.

Outstanding Frother!
Color: Space Gray
Exceptional! This frother is in another league compared to the cheapo push button frothers. The motor is smooth, quiet and powerful. This has an intuitive thumb dial on top that operates smoothly with a wide range of smooth speed adjustment. It’s gentle enough to froth a little bit of milk for a macchiato and powerful enough to scramble 3 eggs. The head is removable for easy cleaning. It’s also rechargeable. I charged this the day I bought it on April first. I use it at least twice a day. It’s September 26th today and I have yet to recharge it and it’s not showing any signs of needing a charge. One minor quibble is that they give you 2 of the same frother heads. They are built so well, that I don’t imagine it ever wearing out. It would have been nice to get a whisk or something different. Not a deal breaker at all though.
