Great product from a great company
Color: Black, Size: Rechargeable
This product works very well. There are several other whips to use also. I absolutely love the cream it makes and that is important so I can enjoy my morning coffee. I used this whisk for quite a while then all of a sudden it stopped working. I wrote to the company to explain. A few days later they sent me a beans new whisk. GREAT item and great company to work with.

Great Frother - almost too powerful
Color: Black, Size: Rechargeable
I’ve been using the Tyohur InstaWhisk milk frother for a while now, and overall I really like it—but I wouldn’t quite give it 5 stars, and honestly it’s because it might be a little too powerful for its own good.
First, the positives: this frother does an amazing job. The single-button control is super easy to use, and I love that you can adjust the speed just by how much pressure you apply. It feels very intuitive, and you can really dial in the exact texture you want. Whether I’m making a latte or mixing something thicker like a protein drink, it handles everything smoothly.
The performance is seriously impressive. On the lower speeds, it creates nice, silky foam, and when you turn it up, it’s incredibly fast—like café-quality foam in seconds. High-speed frothers like this are designed to create rich foam very quickly, and this one definitely delivers on that promise
That said, the power is also what knocks it down a star for me. If you’re not careful (especially when using higher speeds), it can splash pretty easily. The product description says it’s designed to prevent mess with stable low-RPM operation, and that’s true if you stay on the lower settings—but once you ramp it up, you really need to keep the whisk fully submerged or start slow, or it can send milk flying out of the container

Great frother and well built
Color: Black, Size: Rechargeable
I don’t usually write reviews, but since I’ve been helped by so many reviews from others, I wanted to share my thoughts on the InstaWhisk Milk Frother.
This is a great frother. It really whips cream into a tasty, rich froth. My wife and I have tried cheaper battery-operated frothers in the past, and while they worked fine at first, they didn’t last very long. The InstaWhisk feels well built and works great.
Pro tip: The frother may be a little too powerful at normal speed, so you might need to lightly “feather” the power button to keep the liquid from overflowing the cup. Once you get used to it, it works really well.

Great frother/stirrer especially for the price.
Color: Black, Size: Rechargeable
Best one available. Have used cheap ones from the store that work pretty good, but batteries are a pain. This is rechargeable and it has a push button that allows you to start it right away without having to turn it on to start it kind of like a power drill. If you start to press it it goes slow the harder you press the faster it goes. The different attachments are great. We use it for both coffee frothing as well as mixing up electrolyte drinks with water with the included mixing attachment. Crazy powerful and easy to use.

Strong motor. Works great
Color: Black, Size: Rechargeable
I really like this frother. The fact that it’s variable speed, rechargeable, and can spin at a high rate are all great features.
I use it to blend collagen powder and cream into my coffee every morning. Also sometimes use it to
Blend drinks. Strong motor.
Like that the whisks are removable for cleaning and that it comes with different ones.
