Hands down, the BEST handheld frother I've ever used!
Color: Black
Hands down, the BEST handheld frother I've ever used! I got the black one, but any color will have the same results. Over the past 12 years or so, I've used so many different handheld frothers and they've ALL fallen short of expectations for quality, longevity, power, features, and usability. I've used everything from cheap, $15 models to $50+ models and everything in-between. Some with fancy attachments for various types of mixing, frothing, beating, whipping, etc. Some with rechargeable batteries, some without. Some AC powered, some with fixed whisks, some with detachable/replaceable whisks, some with stands, etc. NONE have been spectacular. Most broke within 6 months and got tossed. ALL were major disappointments in the end, including the "revered" Zulay models of which I tried several. I finally found this Maestri House branded, variable speed frother with detachable / replaceable whisks and got one to try. I was literally on Cloud Nine the first time I turned it on. Like, WOW! Not only was it FAST on the highest speed, but it was powerful enough to churn right through milk, eggs, cream, etc, without bogging down like many others. This thing makes milk froth like a milkshake and Matcha Lattes like nothing else I've ever experienced. I used to have to sift my Matcha, then whisk it in hot water, then froth milk and then blend them together to make the perfect latte. and if the milk was cold (my preference), pre-whisking in hot water was a must to avoid lumps. However, with THIS frother? I literally pour my milk into a tall tumbler, drop in un-sifted Matcha powder, and spin up the Maestri House frother at first on a medium low speed to get it mixed, then jump straight to the highest speed to really whip that milk and match up. After about 30-45 seconds, I've got the thickest, richest, smoothest, most aerated latte around. And NO LUMPS at all!!! What a time and dish saver! And cleaning? I just run it under hot running water to get the shaft cleaned and then spin it up in a dish with hot running water for a few moments, then spin it on high for a few seconds in the air to dry it off instantly. Now, I'll be honest here, too. The specs say it can go months on a charge, using it for a couple minutes a couple times daily. Well, I guess it could do that and still spin. But I use it FULL SPEED, churning hard for at least a minute a couple times per day. After about 2 weeks, I can start to notice a speed reduction so I just plug it back in on the charger. All things considered, this is still better than all the other handheld frothers I've used over the years. After using the heck out of this thing for the past 7 months, I've even decided to start selling these in our Japanese gift shop. The manufacturer is has been very responsive both in customer support (I called them about an issue I thought I was having, and they called me back with a couple hours even though I didn't leave voicemail when they didn't answer right away) and in reseller support. I have to give these guys an A+ for responsiveness and quick resolution when problems might arise. HIGHLY recommended!!

Great Addition!
Color: Black
Why did you pick this product vs others?: I just started a powdered drink routine recently and was having a difficult time mixing it with water. I would consistently end up with small nuggets of mix making it unenjoyable to drink. I knew I needed a mixer and was glad I found this device when I did. It works perfectly! I like the fact that it comes with its own stand and included two mixing heads. It is solid, well-designed, and you can feel the quality when you pick it up. The variable speed of the mixer is perfect for ensuring that everything is blended well. I haven’t used it to “froth” anything yet, at least not on purpose, but I accidentally found out that it can do that well. This is a great addition to our kitchen and is very easy to wash after use. So far…no issues. Highly recommend for those of you looking for the right tool to make sure those protein mixes aren’t full of unmixed nuggets.

Low foam
Color: Black
Love this frother. It is great quality and the turn speed is amazing. My only issue is this. It comes w 2 wands and they are both singles. The single is great for stirring things up. It does not make a lot of froth and for some things it’s perfect but sometimes I like a lot of froth and I wish it either came w a single and a double or you could purchase a double separately to intermix. I don’t want to buy a whole other unit just for the double. I wrote to them bc the double frother they sell doesn’t look as good as this one but sometimes a girl needs a lot of foam and sometimes th stirring is perfect.

Best stirrer I've used, and I've used a couple
Color: Basic Black Frother, Size: Basic Frother
Really good stirrer / frother. I got some powder supplements that need to get stirred in a measuring cup every morning, this works great. It is waterproof. There are 3 buttons, for stirring speed, the low one works pretty good. There are 2 other attachments, which are easy to pull off and switch. It came partially charged, so I could use it right out of the box. Very good product.
