Review on BlackVue DR900X-2CH With 256GB MicroSD Card 4K UHD Cloud Dashcam Built-In Wi-Fi, GPS, Parking Mode Voltage Monitor LTE Via Optional CM100 LTE Module by Drew Cage

I purchased 4 of these cameras and all but one are working. The camera that was purchased from LECTRO (Battery Boy) was DOA so I was able to return immediately through Walmart. The replacement camera LECTRO sent worked for about 3 months before it started powering down and would not stay on. None of the other three cameras are having issues in the vehicle that this camera was installed. I contacted Blackvue and was informed that I had to work with the distributor in order to get a warranty replacement. The distributor LECTRO had me send the camera to them (I paid $20 Shipping) and they said they would send me a replacement. However they returned the same defective camera to me stating nothing was wrong with the camera. So I had to send detailed videos of the issue to them and then send the camera back ($20 Shipping again) and they said again they would send a replacement. After a month there is no replacement and LECTRO will not respond to my emails other than saying the replacement was shipped. After 10 days the USPS tracking status is "waiting for item" which means they just created a label obviously. It seems to me that the company Blackvue would handle the warranties and not leave that to their irreputable sellers.
