Best Hand-Held Frother EVER
Color: Rechargeable with Storage Stand and Box - Black
I have had many hand-held frothers over the years; hand-held as well as counter top. None of them have really given me the froth that I want which is dense foam to the point that it almost forms "peaks" and needs to be spooned into my coffee. Additionally, the one that I always went back to (hand-held) only lasted for 3-6 months at best before breaking and sometimes it lasted only a few weeks. Additionally, it drained batteries to the point they needed to be replaced every 2-3 weeks. The Circle Joy DOES make thick, dense froth (I use very cold skim milk on the high speed), has 3 speeds and is rechargeable so no more battery issues. Once I froth the milk, I pop it in the microwave for 40 seconds or so to heat/warm it up. It also comes with an attachment for beating eggs as well as an attachment for stirring in protein powders. I don't need the egg beater and I use the low speed to mix in chocolate collagen powder. I just got this frother so reliability is yet to be proven but I figure at $20.00 even if it needs to be replaced every six months ... it is still a winner.

Works well, worth buying.
Color: Rechargeable with Storage Stand and Box - Black
Works really well. I wish the attachments were easier to get off without feeling like you are going to break them. I use a butter knife to pry it off carefully. I like having the case too, it works well if you need to travel with it.
