Tired of using your own tongue to test 9V batteries???
👅👅👅🔋🔋🔋 ouch!

Honored and humbled to announce my latest product:

@gvy_dvpont why would you lick a 9v battery 
@otter it's honestly a pretty good way to see if it's got juice left
@gvy_dvpont why don't you just use like a multimeter or something idk
@otter because then I have to go find my multimeter! I hate to tell ya but this is not uncommon
