Changed 1st review. Product works well!
Color: Absolute Black, Size: Z1 Motor + Batteries
Need to change my review. I WAS putting the batteries in wrong. 🫤 My husband showed me what I was doing wrong. Apologies for the first review.
Doesn't work. I put in the batteries three different times just to make sure I wasn't making a mistake, but it wouldn't turn on.

A Frother that Won't Turn Off? Great Service. Lost Package. Great Hot Chocolate. Worth It!
Color: Black, Size: Z1 Motor + Batteries
I saw this item (or one similar) on an Alton Brown short video. He recommended a frother and I thought "what the heck? If AB recommends a uni-tasker, it must be something good."
The item came in, loaded with batteries and all. I removed the plastic tab that interrupts the power and the unit kicked on. I wasn't pressing anything. It just started and would not stop.
To return the item is not worth the time or money, especially since none of the "free return" options are anywhere close to me.
Called the company and told them what had happened. I spoke with a very nice woman and after I described what happened, her response was not faux sympathy, but "that shouldn't have happened. We'll make it right."
She offered not only to replace the unit, but send a second one free of charge. When I declined the second one, she said "take it for your troubles. Give it to a friend if you want."
The order was sent out. Tracking via USPS was sent.
The package was supposed to be delivered on a Friday, which was great as we were supposed to get cold temps and snow. I was anticipating making frothy hot chocolate.
Suddenly the tracking showed the package being delivered. It was not. You cannot ask the USPS to find a package for 7 days and my local post office doesn't answer the phone.
Disappointed, I started to make dinner and looked out the window and I could see my postal carrier's truck a block away.
I waddled over to the truck and talked to her. She said "I know where it is."
She had delivered it 3 blocks away. Same house number, but different street.
She went and found the package, brought it to me and Bob's your uncle.
That night I made hot chocolate and used the frother.
I was surprised that the long shaft did not vibrate or waiver. It stays true. The speed is fast, but not overly so.
The thing made a difference. It seemed to make the hot chocolate "lighter" and smoother. I threw a piece of chocolate in the mug, waited a little and then frothed again using the frother.
No issues with the frother.
I now had frothy, really chocolate-ly hot chocolate. For kicks and on the advice of a friend, I added a tablespoon of peppermint schnapps and used the frother again.
Best hot chocolate from a mix I ever had.
The frother worked better than advertised.
Woo Hoo!!
Because the first one didn't work, I have to knock a star off of the rating for the product. But the customer service and actual accountability of the women with whom I spoke is refreshing in the world of product support and customer service.
The item is really good and would recommend whole heartedly.

High Quality and Surprisingly Powerful
Color: Absolute Black, Size: Z1 Motor + Batteries
The Pros:
Unexpected Power: I usually know exactly what to expect with the products I order, but this unit really blew me away. It is surprisingly powerful and handles everything much better than I anticipated.
Premium Batteries Included: It was a great surprise to find that it came with Duracell batteries. Seeing a name-brand battery included really speaks to the overall quality of the product and shows they aren't cutting corners.
Solid Build: From the moment I set it up, the unit felt sturdy and well-constructed. It is rare to be this genuinely pleased with a purchase right out of the box.
The Cons:
Operating Noise: Because the motor is so powerful, it does produce a bit more noise than some weaker units. It isn't a dealbreaker, but it is noticeable during extended use.
Bottom Line:
This is a high-quality product that exceeded my expectations in both performance and presentation. The fact that it comes ready to go with reliable batteries is a huge plus. I am very pleased with this purchase.

Great little frother!
Color: Absolute Black, Size: Z1 Motor + Batteries
Works great! I use it for my coffee & creamer, and also my electrolyte mix. Great price which includes Duracell batteries and a hand little stand.
