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.

Works well, long use on single charge, high torque - be careful when starting
Color: Black, Size: Rechargeable
Not the most inexpensive powered whisker bur I've used other Typhor products and found them reliable for the task designed. I fell they don't cheap out on the rechargeable battery so I don't fell they will catch fire, as we are hearing about from other cheaper rechargeable items. I liked 2 things about this model the speed control is by a pressure single switch which I can control, not just pick speed 1,2,3. The swappable tips allow for different uses. I don't drink coffee but use the item to whisk eggs for an omelets and it has the torque to mix them without effort. In Fact need to only use half power else it will splatter out of my mixing vessel.

I love it!
Color: Black, Size: Rechargeable
This thing works great! It holds a charge for a long time. I love that it has different attachments. I use it mainly for mixing powder into my drinks. It is very powerful. The speed is adjustable too. It feels good to hold too. It lights up when you squeeze the trigger and when it starts losing charge, the light bar gets shorter. I highly recommend it.

Perfect all-around frother, stand keeps it nice and neat on the counter within easy reach.
Color: Black, Size: Rechargeable
Rechargeable, lightweight, variable speeds and optional whisks all make this the perfect item for your kitchen. You can quickly froth milk for your coffees, whip a small batch of whip cream, and even make mug cakes with the hook attachment. The price is very compatible with the competitors, but the ease of use makes this a top choice. The variable speeds makes it much better to control than the push button ones. When you let go of the pressure switch it turns off, no need for a dedicated on-off switch. Having the pressure switch on the top makes it extremely easy to use! It fits very comfortably in the hand and with the metal stand, looks quite nice on the counter, ready to use at any time. I highly recommend this InstaWhisk!
