When I inserted my SD card into my K2 it slid in under the slot instead of into it. I emailed Innovv and was instructed to open the DVR by removing the screws. Has anyone opened one of these? There is no way the DVR is waterproof. For starters, the open air around the SD slot provides water access to the circuit board. And that flimsy rubber door over the slot would not meet the definition of waterproof given that it won't even stay closed on mine. There is a recessed groove around the plastic ( I don't remember if it was top or bottom half or both) that could potentially be fitted with an o-ring, but there is no o-ring. Even if there were, it would not solve the exposure of the SD slot.
