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.

Works well, worth buying.
Color: Rechargeable with Storage Stand and Box - Black
Works really well. I wish the attachments were easier to get off without feeling like you are going to break them. I use a butter knife to pry it off carefully. I like having the case too, it works well if you need to travel with it.
