What happened to the battery already having life, I was a little annoyed that you need to charge the battery before using it. I do not recall needing to do that growing up but then again I never handled that as a kid. It would have been wise if they would have stated on the package to use the product correctly, so people would know they needed to put it on the charger. Most products do this including the
best acne treatment. Had it told me that the battery needed to be charged first I would have done that, so I can say I am a little unhappy.
