It froths, but is not dependent
Color: C-Black, Size: Model C Rechargeable
While this frother does “froth”, it has many more cons than pros. The ONLY pro is it froths. The cons—only good for a traditional coffee cup. It is not water proof, and the instructions say to keep the “unit “ dry. As you froth, the liquid naturally raises height. If you are trying to use a Togo coffee mug, or thermos type travel mug—it only works well if done it three or four levels to ensure keeping the motor above the liquid. The “rechargeable “ function DOES recharge, however- it may last 1use or a few. It’s VERY inconsistent. And does not seem to be related to how long you allow it to charge. Overall—not a good buy. I had mine maybe 3 months before it quit working. And at 2 months it started becoming spastic. Even after just being charged-it wouldn’t even froth 1cup. AVOID!!

Easy to Use and Works Great
Color: C-Black, Size: Model C Rechargeable, Color: C-Black, Size: Model C Rechargeable
This milk frother works amazingly well! It’s powerful, easy to use, and creates rich, creamy foam in just seconds. The rechargeable design is very convenient, and the battery lasts a long time between charges. It feels sturdy and well-made, and cleaning it is quick and simple. I use it every day for my coffee, lattes, and hot chocolate, and it has exceeded my expectations. If you’re looking for an affordable and effective milk frother, this is definitely a great choice. Highly recommended

Love it!
Color: C-Black, Size: Model C Rechargeable
Love mine! No more batteries. I make at least two cups a day and froth my creamer. Love the fact I don’t have to recharge very often.
