Perfect

Really really easy to set up, just some static film and running some wires around. Camera quality is really good for the price. for anyone reading this before buying it though, BUY AN SD CARD! It doesnt come with one in the box!

Better Than Expected

Compared to my cheap dashcams in the past, this one blows them away. It was easy to install and there was plenty of cable for the front and rear cameras. The android app is intuitive and easy to use. It's easier to apply setup changes via the app vs using the buttons on the device. I'll definitely purchase another for my other vehicles.

Awesome Value for Money

All you could need to setup the dashcam in the box with extra mounting options and accessories to hide cabling plus an informative instruction manual. Quality is great day or night, and lots of great features for the price. So glad I chose Viofo

Great Quality Dash Cam

I decided to purchase the A129 Pro Duo after doing research on various dash cams. I am happy to say I made the right choice.

The recordings are crisp and cords are very minimal since my camera is hard wired to the battery.

Best dash cam I’ve owned!

Upgraded from Nexar to this model and it’s amazing. Just as easy to install, extremely clear picture. Better sound. And the best part, a rear camera!
