This is the second dashcam and battery bundle that I bought from blackboxmycar. First I bought years ago for my daughter's 2014 Subaru Outback. Now, for my car, a 2018 Ford Expedition Max. I buy dashcams mainly for "just in case" of an accident. I want to be able to have some documentation of what had happened just in case of any legal issues.
First off, customer service was awesome. At the time of my purchase, the BlackVue battery was on backorder. They immediately e-mailed and called me to let me know, and gave me options to wait for the battery or send the camera first and battery later separate, both at no additional cost. I e-mailed them back, and got quick answers back. Awesome. They send by UPS with signature required, FYI, so make sure either you or someone can sign for them.
Installation is very straight-forward, even the battery install. For the Expedition, I used the fuse for the heated steering wheel since it's a purely accessory circuit without any delayed programmed into it. The cord for the rear camera was more than long enough for the Expedition Max, which is the extended version.
Anyway, if you're in the market for a dashcam, you can't go wrong buying this BlackVue unit with the battery, and you can't go wrong buying from blackboxmycar.
