Light Activated MP3 Recordable PCB Sound Module USB Downloadable Music Chip for Greeting Cards-with Lithium Polymer Batteries and USB Cable

Battery life is short. I accidentally left it on in a dark place and it drained the whole battery. The battery is not rechargeable

This device performs as advertised, but randomly stopped showing up when plugged into computers, meaning I can't change the sound it plays or the volume of the audio. I think it's also worth noting that the product I was sent is not the exact same as the product shown in the product's images (see attached photo). The differences are so minimal that they shouldn't be a problem for most buyers, but the fact that the connection between the battery and circuit board is a cable connector rather than a direct solder (as depicted in the listing's images) means that I can’t modify the device with my own longer lasting power supply.Update: tried giving it one last attempt before returning it, and the included USB cable CAUGHT FIRE just from being plugged in to the computer for five minutes. This product is downright dangerous

The default noise sounds fine but I tried to connect with a cable to my computer, and it doesn't show up any storage or anywhere to download/reupload custom MP3's

I have a fremisis(nemesis freind). This guy is a 6'3'' freshman in highschool, while I am only 5'4''. Therefore, when I saw this ingenious product, I immediatly purchased it, secretly placed it in his locker, and it worked like a charm! Thankyou so much for the amazing product!
