I ended up using these for a cosplay project, and damaged the "off" functionality in one of the buttons. I was worried it would die in the 6h I needed the lights to work. It has been over two days and 8 hours, and the thing is still shining. Despite being slightly annoyed at the now illuminated ceiling in my bedroom, I've gotta say... im very impressed.

I purchased the Flat Lights Single Pack. I trusted the company since it was advertised that if we do not like the product they will do it right. I received the lights, but the LED is so weak that nothing glows. So pretty much a useless product. I read the fine lines in the receipt in the package for return instructions and there is a 25% restocking fee. So much for making it right. So the product is $7.8, shipping is $9.01 - with 25% restocking fee the return for a falsely advertised product will be $5.85. Not worth the time to go to the post office or the gas to get there. And I do not know if we also pay shipping.
