A month ago my wife was in an accident in her car, another driver went through a red and t-boned her Subaru. Police officer took the report and said with conflicting stories from both drivers and no dashcams it would be assessed as her failing to clear the intersection.
The next day I ordered a DR590x-2CH for her new car. I had a DR590-2ch for the last 3 years in my Tacoma and love it, it's been extremely useful and I've provided clips to others when I see accidents. Parking mode is great, I still use a PMP but look at battery packs as the next upgrade.
I installed the new cam and it's already a relief to have it. We are headed out for a two week roadtrip and I'm glad that it's coming with us.
Blackboxmycar is my go to, I recommend them to everyone, and they've helped me with selecting the cam, getting accessories, replacing stickypads, and helping with setup. They reply same day and have helpful answers every time. I'd give them 6 stars if I could.
