Calamp support seems to be shi*.
I remember that i requested some infos but never got an answer. So no device for us.
I am testing at the moment HW from Kingneed (chinese!) but since 2 months the device is in my car, on my desk, back in car and configured to send when device is moving. So movement sensor is on (which costs realy a lot of power) and battery still 50% full (after two months).
It has strong mangnets, a IPx56 case (should be ipx7 but i dont trust), a 15400 maH LiIo battery (beware of transport and shipping, DHL etc. starts to make troubles with transport of LiIon Batterys) and sample price was 134 USD or so...
But Still: really nothing perfect at the market!
