This battery broke after about a month but I loved it up until it stopped working.
I thought the price was too good to be true, but I've dragged it everywhere with me for over a week now and it hasn't died on me once. Love it
Love it. Really helps with stress.
Definitely good for what it is. Takes a little too long to charge but it also has a long battery life.
Definitely recommend this product. Voltage is adjustable on the bottom.
