I asked in the main sub , and that was the answer I <| sep |> I ' ve seen this exact thing before . I swam in the middle of a bunch of bioluminescent plankton while in Cambodia . It was so trippy and cool ! <| sep |> It ' s been about 8 months still works since april on duracell turbo max 3 months officially on stock alcaline batteries . It has been heavily redesigned , all electronics is 3 . 3 v now and there ' s no usb connection anymore , just bluetooth ultra low power BCM 20730 , BT 3 . 0 . No charging either , just batteries and MicroUSB as backup power . <| sep |> Sure , but I thought you ' d like me to have some useless frustration at trying to avoid eating my hair while exposing my behind in an awkward and humiliating position .
