I bought this frother, along with the white as a gift because I have one and use it all the time. They are amazing and a great investment for $10. Not only does this frother work great for coffee, but it is very handy for other things. I make my kids instant breakfast drinks in the morning using a powdered mix along with a protein powder. Rather than dragging out my blender, I just stir the drink with my frother. It has no problem mixing everything completely and the kids like the "froth". I've also used it to "destroy" some flour lumps in gravy when I didn't get it mixed in completely. It whips eggs for scrambled eggs. Granted, it's not high powered enough for some jobs, but overall, this frother is one of the best $10 gadgets I have ever bought. At this point, I'd be lost in the morning without it!!
