FOLCONROAD Car Dashboard Clock Adjustable Auto Thermometer Vehicle Temperature Gauge with LED Backlight 12/24 Hours -20℃ to 50℃ Black Without Battery,only in Celsius NOT Changed to Fahrenheit

The display is very good, especially with the backlight. Would have rated it better if the setting instructions were correct and the A and B buttons worked consistently. Had to reverse the button functions to get it to work. Also the battery was a little loose until I bent the contacts out for better connection. It seems to keep accurate time. During setup it requires the year and date, yet there is no way to display this.

It serves its purpose, the adhesive that came with the clock didn’t work so I had to get a better quality tape. It would be much better if there was a light option so that it would stay on all the time rather than having to press a button while driving.

As said before, A and B buttons are backwards and they dont always work. Absolutely no mention of what battery to use and battery doesn't fit properly either. It's better than nothing now that I've got it set properly.

Easy to use and as described.

I dislike because I can’t get Fahrenheit temperature.

This suited my needs when my car clock started giving me trouble. Was easy to install and is easy to read the time during the day or night. I knocked off 1 star because of the temp reading being in C only as I happen to agree with many reviewers that if sold to the US, US standards should be available. However, I bought anyway because I can feel and adjust the car temp just fine without seeing what the actual temp is and would really prefer if it wasn't there at all. For the purposes of the clock only - it works just fine and can easily be seen at night which few others of this size could do.

I ordered it and the light did not work. It was a nightmare to return because the UPS store by me closed and I needed the actual label printed to send it back. After trying to contact Amazon several times, i finally got to send it back for a replacement. The replacement worked great for a week, then it kept resetting to 12:00. I can't ask for a return because it is telling me that it was already replaced. Do I seriously lose my money because of a poor product and return system??

I like that if you hold down the button for 5 seconds, the light goes to a dim light setting that stays on and I can read in the dark without leaving the brighter, single-touch light setting on. It says the dim light will go off in about 4 hours, but I always just press it again to turn off the light when I get to work. Keeps good time so far. When I got it the instructions said to hold down the A button to set it, when actually, holding B down worked for me. Anyway I would buy again. BTW thermometer is celsius only, no fahrenheit option. 9/5 C + 32. Ha.
