I got 2 of these about 3 months ago. Worked fine and good enough for my usage. However, yesterday one of them was intermittent and failed to turn on, both were fully charged. Sometimes it will turn on, you can here the clicking of the switch, it goes thru all the modes in the White and Red, but skips Green completely. Bought them thru Amazon, and there seller contacted me requesting a video, so we're going thru that now. Was just curious if anyone else had issues with theirs.
