• Don't let it get wet/stay wet. Mine has just died after only a month of commuting. It got wet maybe twice and the usb port underneath is completely rusted

  • Just checked mine. I've had it for about the same time and done 6-7 wet commutes with it, no sign of water ingress or corrosion yet but I'll keep an eye on it. I think if it fails I'd buy another one, really happy with the brightness and battery life. Plus the flash mode is SOS in morse code which is pretty funny.
