Review on Vantrue M2 2.5K Dual Mirror Dash Cam For Car, 1440P Front & Rear View Waterproof Backup Camera W/ Sony Night Vision, GPS, 24H Parking Mode & Assist - Supports 512G Max by Kendrick Dooley

So installation was not as painful as expected, although installing the back camera was a pain but that isn’t the camera manufacturer’s fault.Thoughts:1.The mirror with the screen turned off is not really effective, which is fine, I just leave the screen on with the back camera displayed but it would be nice if it had better reflectivity with the screen off.2. Weird issues with SD card. Worked fine for a month then suddenly kept giving errors about "slow SD card”. I used a high quality (recommended) Samsung brand and class SD card but apparently the camera was not satisfied. Switched to Vantrue branded (overpriced) card so hopefully that solves it.3. touchscreen could be more responsive, it can sometimes take more than one touch to register.4. Biggest issue - the firmware needs a way to disable the big red LOCK icon when you hit a bump or lock video or whatever. It times out eventually but in the meantime obscures vision. Same with the "slow sd card” alert. NEEDS TO BE LESS OBTRUSIVE it blocks the view which is a safety hazard.5. the backup camera parking guides are worthless. you can’t adjust them enough to be accurate. Not useful at all.UPDATE: Originally bought a Samsung SD card for my vantrue dash/read cam. It was the proper rating and quality card, and the manual even recommended it. However after a month it suddenly was showing errors "SD card slow" and it was crazy annoying even tho it seemed to be recording just fine. So ordered a WAY OVERPRICED SD card from Vantrue and haven't had the error yet. Very annoyed with what is clearly a flaw in the camera to favor their overpriced cards.
