Review on 💨 innobay USB/Rechargeable Personal Fan with LED Light - Quiet & Powerful (4-inch, Black) by Joshua Talbot

The instructions say to properly align the positive and negative battery posts. Seeing no positive or negative markings on the battery, I removed the pink cover and found no positive or negative markings underneath. Apparently, there was no need to remove that protective pink coating and you just need to somehow figure out for yourself what the pros and cons of the battery are. Now I have a defective battery. More detailed instructions would be nice. UPDATE Got a spare fan. Turns off a few minutes after turning on. I'm tired of getting junk from Revain.
