I click and its not powered upon opening the package. Okay so there was no indicator stating charged. I charge for 5 hours via USB and see a nice blue light emitted from above bulbs. I click button and it works while connected to laptop/desktop. I remove to use on book and click, I click, I click, I slam, I punch, I bash, I throw across the room and still get no light. I reconnect to laptop/desktop USB and see a lovely blue charge light which generally indicates done charging. I push button and it lights. I remove and push button but nothing happens. I throw in the trash and consider myself lucky this was only a 20 dollar set back. How disappointed I am.
