Update: I purchased this item in April 2021, it stopped working. I loved it and used it every morning. I was trying to contact the seller but cannot find contact information. This was upsetting because I used this with my protein powder. If you purchase this frother be aware it will not last.
I use this daily, only charged it when I first got it over a month ago. The different levels of controlled power is excellent. I cannot speak to how long it will last yet, but if I have an issue I will update my review.
