I love this mixer
Size: Basic Frother, Color: Black
I love this mixer. I don't know how we got along before we had this. We have had this small hand mixer for 2 years, using it several times every day, day after day and it finally stopped working and I am ordering another one right now. I can't live without it. I make our bullet coffee with it. My wife makes her morning shake with it. I could go on and on but I need to get another one ordered right now.

Works perfectly!
Size: Basic Frother, Color: Silver
The first unit I got, the charging LED was not working so I don't know if the unit is charged. I returned the unit back to Amazon and got a brand new unit the next day. Great job, Amazon! The 2nd unit has been perform perfectly. I use it to whisk eggs in the morning to make French toasts, waffles, pancakes. All comes out perfect! Also, the mike froth for my morning latte and cappuccino. Don't under estimate this small unit, the spin is fast for high!!! I saw some negative review on the durability of the unit. I hope this is not the case. I'll update if anything changes. As for now, highly recommended!!!

Epic. Works great.
Color: Black
Works great every day. Super powerful and smooth compared to my old battery powered one. The shaft is much thicker and is more securely positioned so I can't imagine it becoming tweaked off balance like my old one. And it comes with an extra mixer attachment! I imagine I've put that away for a long time, but we'll see. Easy to turn on and off with one hand, but I can imagine it being less easy than a simple push button for someone with decreased thumb dexterity or mobility. I do wish the lowest speed was slightly lower, but it hasn't caused any splashing or other detriment. The speed adjustment is very smooth and power is abundant. Love the stand, Usb c charge port is solid, battery life is excellent.
