Review: Value for money at 13k for dual - Quality is amazing. Must have for those who want to be remain safe in this ever growing rowdy traffic. Records everything perfectly. Night vision is perfect. Even picture taken is good. Make sure you turn off emergency recording or every bump will make it save video. Picture saved is also good. Installation is good. Features and app are easy to operate.
Review: Some things could have been better! - The best thing about this dashcam is it's video quality- day vision or night vision - it's crystal clear, crisp with excellent colour reproduction!! GPS is reasonably accurate! Now, something that's not so cool! The wifi connectivity and video download speed is crappy!! And most of the times the download stalls midway and gets cancelled! Built quality is good and foam factor is compact and smart! The app could accommodate more features Overall a good product but needs more improvements.

### ⭐⭐⭐⭐⭐ Rock-Solid Dash Cam with Great Clarity, Reliability & Must-Have Safety Features
*by R***A on 16 June 2025*

I've been using the 70mai A800S True 4K Dual Channel Dash Cam for over 2.5 years now, and it has been a reliable and valuable addition to my car. The front camera records in sharp 4K quality, even during low-light conditions. However, 4K recordings consume significant storage—my 128GB SD card could only store 3–4 days of footage. I later switched to 1080p, which still offers great clarity while extending storage capacity to about 8–10 days, making it more practical for everyday use. The rear camera offers excellent 1080p clarity and works well for continuous rear coverage. Just note that it functions independently and isn’t linked to your car’s stock reverse camera system. I chose not to use the hardwire kit to avoid putting extra load on the car battery, and I’ve had no issues—especially since my car is parked in a secure area. Installation was simple and hassle-free. The built-in ADAS features like Lane Keep Assist and Forward Collision Warning are useful, but they can occasionally be a bit intrusive during normal driving. The companion mobile app is user-friendly, though there’s still room for improvement in terms of speed and UX. One of the best features is the event-based recording — the camera automatically captures a 1–3 minute clip whenever it detects a significant impact or jerk. This has helped me immensely in revisiting important footage related to road rage, accidents, or unusual activity around the vehicle. I received a fully authentic and functional product, and I’ve faced zero issues over 2.5 years of use. For anyone considering a reliable, high-performing dash cam, I highly recommend getting the latest version of this model without second thoughts. It’s truly a road companion and a potential lifesaver when it matters most.
