Like Chris I’ve got a DR650GW-2CH, been absolutely fine. My last one the lipo battery had to be changed but that’s a characteristic of the battery when it gets hot in summer.
I used to leave mine on 24x7 but now it’s usually 6 hours after I park, already paid for itself when some goon in work took leave of his senses and with trying to make a point, parked within a mm of my drivers side , only he misjudged and actually rubbed the rear wheel arch, then denied all knowledge, when I presented the video footage they paid up.
