So annoying that Apple started the trend of no chargers, they lowered their price and all the other have to follow. Warning!! this comes with a USB C to USB C lead, yes the cool new cable that is going to change the world. Even apple forced to use yay, the same lead for EVERYONE. BUTTTTT if you do not have a USBC charger and only a USBA that is the original BIG sqaure edged one, this will not work. You need to buy a USBC charger to use this. Other than that, I can't see if it kills the bugs as I cant see the bugs, Simple open the case to load , close and press the button. Then 10 minutes later it beeps back.
