10$ more than it was last year when it was on sale but still a good deal IMO.

Customer Reviews:
Previously had the A129 Duo, A119 v2 and A119S versions by Viofo and have always enjoyed their products. Decided to try the A129 Pro Duo and this one doesn’t disappoint. Great upgrade if you want to start recording 4K on the front (rear camera is the same as the A129 Duo). I like that Viofo is an active member on one of the major DashCamera forums and they listen and respond to their customer base for issues and wishes the users provide regarding their products. You really can’t go wrong with their products. Word of advice, make sure to invest in a good brand name and fast memory card for use with any dash camera. It’ll save you a lot of headaches.
