Bests & Worsts Reviews from Amazon

Okay, so I planned a very important business trip and due to all the electronics and paperwork on the car I wanted a cooler with no ice/water, so I decided to buy one of these. I made sure to leave it sitting flat for a few days so nothing was out of place internally. I then ran it in, inside, for 5 days to make sure there was no issue. I notice the temperature varied about 8 degrees. Not a big deal. I packed the car up, and literally made it not even 5 miles before it started flashing wildly and finally settled on F7. I turned around and went home. I hoped the user manual would help.... Manual? It’s a damn trifold pamphlet, not kidding, picture included. Error code F7... temperature sensor, please check sensor terminal.... no where is the location disclosed, in the manual or on the net. Speaking off this company seems to be Amazon and Alibaba only. So am I supposed to take this apart!?!? If so, where are the diagrams, the schematics? Verdict: This is a China only company making junk that is no longer dirt cheap, but still made with the same crappy QC they’ve always been know for. I’ve decided I’m not doing HVAC repairs on junk. Returning this and frankly I hope this costs them as many sales as possible.
