Very powerful. I bought it to mainly mix my collagen, etc. into my coffee, but I even used it to make homemade ranch dressing & it worked great. Highly recommended I just wish the whisk was removable to make cleaning easier.I love this thing I use it for my coffee, to scramble eggs, to make bottles for my son, you name it.Worked great for about 3 months then slowly lost power and died. Took it apart and checked continuity, good, switch, good, motor, BAD. unfortunate as it is a great idea.UPDATEI want to add that the vendor replied promptly to my complaint and sent a replacement. I would buy again.Love this milkfrother. It has Great-Power Which makes nice frothy drinks love it!The Milk Boss powers up milk to a thick froth in seconds. I even blended honey and it blended perfect! Love it!Love it!Love it! Once you have one you realize everything could use a little mix?Simple and easy to use!This little frother works really well. It is powerful and easy to use. I especially love the stand that comes with it and all of the stencils that also come with it are adorable for making designs on top of your beverage.It’s easy to clean too. I just turn the frother end on for a couple of seconds in soapy water and then rinse and hang on the stand.Word of caution. This little tool packs a punch. Don’t touch the frother when turned on as it hurts ? Live and learn.Also, don’t fill your cup to the top before frothing. The frothing will make the level rise.Enjoy your new tool if you decide to buy. I love it. I actually bought one for my sister after trying mine. I definitely recommend it.Great buy and quality.Easy to use lots of power easy to clean, having a stand is awesome
