Great, wish it had a manual option
Color: Black
Strong whisk that does the job well! Great volume on froth and easy to use and recharge. Holds a charge well. I use mine about every other day and charge it about once a month. Does not have a stand but I keep it in a drawer. I did wish it had a manual function but the timer seems to get it just right.

Good bag for your buck !
Color: Black
The quality of my foam with this this is amazing! I even use it in stuff that already has ice in it and it breaks up my ice ! The charge lasts awhile . Great value for your money . I’ve bought multiple frothers off amazon and this is the only one that’s held up this long .

Poweful!
Color: Black
Very powerful!
I'd gotten too accustomed to my old one with just a single metal spiral roll and so BOY, is this powerful!
I'd also gotten accustomed to the on button being just an impulse button and not a solid "ON" so the first time I used it, I had coffee everywhere. I learned quickly to turn it on and then off right away. I do love how is recharges via USB port. Also the directions are helpful because the actual frothing bar was harder to push all the way into the body of it than I'd anticipated.

Foam/froth galore
Style: No Stand, Color: Black
This frother can't be stopped from making froth/foam. It must go 2-3 times faster than my previous one. Easy touseand to clean.
