CHORTAU Dual Dash Cam

I purchased the original about 2-months ago. Up until 3 weeks ago, it worked beautifully. The specs say that it is rated for operating temperatures from -86° to +158°F. I arrived at my work at 6:30 a.m. and left at 7:15 p.m. The outside temperature reached 99°f w/105°f heat index. When I returned to my car and powered up the camera, it worked for approximately 5-minutes, but then shut down and would not restart. I followed all the advice that customer service suggested, but it was dead in the water. There was no haggling on the manufacture's part. After several emails back and forth, they notified me that my replacement camera was on the way. It arrived in 5-days and I love this camera and now I love Chortau's customer service. I would definitely buy this product again.
