"For what it ’s worth i have ZERO car experience and I got the viofo front and rear cam and used the donggar adapter to power it off the rain sensor behind the rear view mirror. ... I watched maybe 2 tutorials, went slow, and was able to get everything in place in well under an hour with no issues. ... Highly recommend, super easy to do."
"The Viofos were easy to install ... my then 16-year-old daughter was able to do it herself."

"As soon as I told her I had front and rear video, she got really excited. The adjuster of the at fault car was less excited about my video but still wanted a copy. My video also proved the car behind me was not at all at fault so I saved her some hassle too. ... I had a front and rear dashcam which all the insurance companies were excited to see. All of them wanted copies of the video. It proved with zero doubt that the first 3 cars were not at all at fault."

"I have the viofo duo. Would not recommend because mine does overheat. ... I was in an accident end of july 2 years ago and it did not capture it. ... The shock of the crash did trigger the g sensor so i have the footage of my car on its side and the recovery process afterwards, but not the actual wreck itself. ... When its not overheated you have tl remember to reset it for it to start filming again. Very frustrating. ... It works good in the winter months but ive left it unplugged since about march ... All i know is it works fine in the winter but anything over 90 i have to reset it everytime i turn the car on. And it wont turn on and let me reset it until its cooled off ... I pretty much gave up on it after months of it not working right."

"I wasn’t happy with how hard I had to hit the car to get it to trigger. ... I feel like it could easily get door dinged and it wouldn’t save the footage."
"it's very inconsistent as far as recording when you need it to"
"My problem is it records too much. ... It’s triggered by any motion so you need a really large card for it to be practical."

"I ended up buying another one as I wanted a 4K camera."
