Hi everyone, I recently purchased this EA4 and was initially very happy with it. But..
I left it in my car in the glovebox for a couple of days, then went to grab it tonight to go out for a walk...
(Gallery):
The button appears to have warped in the heat(!), expanded outwards, then cooled down into its current state
There's some piece of plastic (button?) underneath that rubber button that has come loose and is rattling around in there also, preventing proper operation of the light.
I live in Australia and it's common to get 45degree celcius days during summer (probably 60deg in a car). Is this thing not built to survive such temperatures?? Or did I just get unlucky? Just going to contact the store I bought it from and/or nitecore to ask for warranty, but thought I should bring it up here as a warning/query.
Sad :/
