I am appalled that OTT does not provide replacement lights for its products? I am expected to throw out a perfectly good lamp base and add the the growing plastics waste problem on the planet for Ott's greed? SHAME ON OTT!
I was just given this as a gift and have used it 3 times. Each time, after about 10 minutes, the light mode changes on its own. Then it will power off on its own. I'll turn it back on but it will turn off again. Charging does not solve the issue. When I plug it in, the blue indicator light is solid, not blinking.
I love everything about this lamp except that you cannot know when it is finished charging and that it just turns off abruptly when it dies. It seems to last about one hour without the usb cable, but I think an upgrade that has a low battery light and a fully charged light would be amazing.
