## Questions & Answers

**Q: Does it have atomic features?**
A: Yes it sets itself from the Atomic clock radio signal.

**Q: would it be too bright in a bedroom at night?**
A: No, it wouldn't be bright at all because it does not light.  The numbers are nice and big and if you have a night light on in your room, you'd be able to see the time.

**Q: So this clock will work as not an atomic clock?   Correct?**
A: Yes, I  believe it does not need to check in with the atomic clock in Boulder, CO to keep time.

**Q: How accurate can this clock run when the atomic feature is disabled?**
A: I don't have it on atomic check in and I have not found it to be off at all in over 6 months.  Your mileage may vary.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent wall clock.
*by R***C on July 22, 2024*

This large digital wall clock gives you a lot of information. I have the time, which includes the hour, minutes, and seconds, day of the week, temperature - fahrenheit or celsius, month, day of month, and humidity.

### ⭐⭐⭐⭐ The largest one I could find
*by T***R on November 2, 2024*

This is the largest LCD atomic clock I have been able to find! I like the fact that it auto-sets, shows 12 or 24 hour time, the date, temperature and humidity! May actually get another for my office.

### ⭐⭐⭐⭐⭐ Huge, Easy to read, Good reception
*by E***N on May 22, 2020*

Love the huge 6.5 inch time digits-easy to read from way across a big room. Apparently the big size allows for a big antenna inside-the clock found the time signal and set itself within 2 minutes of putting the batteries in-I did not have to wait for nighttime when there is less interference. Having the day spelled out fully is also a big plus-my other atomic clock does not even show the day. In my case the inside temperature and the humidity seem very close to other devices when put in the same area. Uses 3 "C" size batteries. If you live in Arizona or any other state that does not do DST Daylight savings time adjustments can be turned off-otherwise the default is automatic adjustment for DST changes. Can be set for 7 different time zones including Hawaii-my other atomic clock only has 4. My only suggestions for the manufacturer is to add the options of running it off a 4.5 volt DC power supply so you don't have to keep buying batteries and adding a photocell controlled backlight so the clock can be read in the dark.
