I really love this clock after my last atomic clock quit working after about 30 years. I like how it gives both the indoor and outdoor temperature, moon phase, and it's easy to read. The reason I gave it 4 stars instead of 5 is because it kept going back to standard time instead of daylight savings time even though I had the DST in the on position. Eventually I had to turn of the atomic function so it would stay at the correct time. Otherwise, it's a great clock.

I purchased second unit after using this device for a few months. The set up for this device is relatively easy. It's nice to have a clock that syncs with WWVB, a longwave time signal radio station near Fort Collins, Colorado and is operated by the National Institute of Standards and Technology (NIST). The time is accurate to within a second. Both the indoor and outdoor temperatures appear to be accurate. The only downside is that the temperature transmitter is exactly the same for all units, so that only one temperature transmitter can be used.

It’s accurate & reliable so the only thing missing is that it doesn’t glow in the dark.

Beautiful clock with large, easy to read numbers. Outdoor probe works well too.

No back light like I thought.

Works great easy to set up

Like the temp features of both indoor and outdoor.

Accurate, easy to set, large clear numbers easy to see from across the room. Excellent value.

Great price love the large numerals

Was easy to set up and understand. Really big letters and numbers. Easy to read. Great item.
