Great upgrade compared to others
Color: Rechargeable with Storage Stand and Box - Black
This frother is far superior to other hand held versions we’ve owned. The attachments are much sturdier and don’t bend as easily (which made the others we’ve purchased quite useless). Rechargeable battery seems to last longer and provides plenty of power even on the lowest setting. The little wisk easily whips up eggs for a morning omelette and frothing cream and mixing powder into drinks are super easy with the other attachments. Finally, the stand is actually sturdy and balanced enough that it doesn’t easily tip over.

Three froth/blend options, rechargeable, comes with container
Color: Rechargeable with Storage Box - Silver, Color: Rechargeable with Storage Box - Silver
I watch a gentleman online who always talks about how in his 40 years he didn’t know x, y, z, and ends with “ain’t no way.” He made this 3-ingredient — 4 with ice— iced coffee, and used a handheld frother, so after shopping for ingredients, I went in search of a frother. What I liked about this one is that it’s not battery operated, but instead is rechargeable. It comes with three attachment, one of which I can use for cake batter, whipping up eggs, making homemade whipped cream, and also sauces and gravy. It also has a case so I am storing it with my coffee paraphernalia. It has three settings and I used the high setting. As you can see it really froths up the ingredients. I’m very pleased with my purchase and thought about all the times I need a slurry of water and cornstarch to thicken soups and stews. I don’t know the charge life yet, but so far, so good. What you see in the cup is 2 tablespoons of sweetened condensed milk, 3 teaspoons of instant espresso, and 2 ounces of water. Then you add the ice and your creamer, half-and-half, or barista lover’s oat milk, and you’re done. Not too bad, as my grandpa used to say.

Great product
Color: Rechargeable with Storage Box - Black
It’s great! Very powerful, even on low speed. Mixes fiber, and powdered mix-ins very well as well as frothing milk. Nice sturdy little case to keep the components in. Stays charged for a long time.

Best Hand-Held Frother EVER
Color: Rechargeable with Storage Stand and Box - Black
I have had many hand-held frothers over the years; hand-held as well as counter top. None of them have really given me the froth that I want which is dense foam to the point that it almost forms "peaks" and needs to be spooned into my coffee. Additionally, the one that I always went back to (hand-held) only lasted for 3-6 months at best before breaking and sometimes it lasted only a few weeks. Additionally, it drained batteries to the point they needed to be replaced every 2-3 weeks. The Circle Joy DOES make thick, dense froth (I use very cold skim milk on the high speed), has 3 speeds and is rechargeable so no more battery issues. Once I froth the milk, I pop it in the microwave for 40 seconds or so to heat/warm it up. It also comes with an attachment for beating eggs as well as an attachment for stirring in protein powders. I don't need the egg beater and I use the low speed to mix in chocolate collagen powder. I just got this frother so reliability is yet to be proven but I figure at $20.00 even if it needs to be replaced every six months ... it is still a winner.
