Highly recommend!
Color: Gray
Love this frother!!! Purchased to replace an Aerolatte that stopped working after a reasonable period of use. Right out of the box, it was charged and ready to go. I’ve been using it daily for about 5 weeks on the same charge it had on arrival and it’s still going strong. Love the variable speed and easy to work with one hand. And this baby can froth! It froths far better than our old Aerolatte. Also love the rechargeable feature so no more AA batteries wasted. This handy kitchen tool makes my morning coffee a true highlight. Highly recommend the Maestri milk frother!

Best Frother Ever!
Color: Black
Great little frother and very powerful after just one charge. I haven’t charged it since the first day and it is still going strong after 3 weeks. I use it daily for coffee froth, but have used it for mixing other things as well. It works great on mixing drink powders into water and for making salad dressing from scratch. It’s one of the best things I’ve purchased on Amazon for kitchen tools. My old frother ate through batteries and was 1/10th as powerful. This one really is amazing. Great quality heavy duty but still small machine. Extra attachment heads are also a bonus.

Very good frother that gets the job done extreamly well
Color: White
I hvae used this frother primarily for smoothies and coffees. Each time, it does a wonderful job.
Deducted a star for the location of the speed control which is ontop of the device. It's akward to use one handed while attempting to control the speed, athough it's advertised as making it easier. It's not!

Good quality
Color: Black
Have used the frother 5 days in a row. It comes already charged. Fingers crossed no issues when I eventually have to charge it.
I love everything about it. It’s worth a little bit of extra money as you can control the blending power from slow to fast. Easily held with both hands to coordinate. Today for a change I elected to just add a touch of bourbon caramel syrup to my oat milk -an excellent choice!
They give you two attachments which is helpful. I’m not hard on my kitchen appliances but it’s good to know I have an immediate back up if needed. I rinse frother attachment out immediately in a cup of warm water and air dry on a towel. At this point, I highly recommend.
My next adventure in the kitchen will be Matcha tea. I will use the bamboo whisk for the actual tea. If I decide to add oat milk to the top,(such as for a cold latte) I will use this frother.

Higher quality then I expect, very satisfied
Color: Gray
High quality overall, very high powered. It looks really fancy and elegant. The adjustable speed knob on the top is really great. The stand looks really nice but isn't the best design because it is easy to knock over when you take it out, that's my only issue with it.
