As others have complained,the battery was junk. Wouldn't turn on unless plugged in. So I dis
assembled it and sure enough battery was leaking. I had to take apart a pair of old airpods to get
the battery bc it was the same size. Un soldered the bad one and soldered in new one. Now it works
like it SHOULD have when I received it. So for the price you pay for this it should not arrive
broken. 1 star. The actual effect, 5 stars
