Pretty good, but not nearly as useful as the older model which had a sunny/cloudy/rainy forecast instead of the moon phase. Really, who cares about the moon phase?

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.

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.

At this price, I didn't expect too much. It has a large, easy to read display, the usual atomic features plus moon phase and outdoor temperature. Very well made, and the clock receives atomic updates and the outdoor temperature updates in my concrete basement. Great job Sam's Club

I purchased the La Crosse Technology Curved Digital Atomic Wall Clock model S74870 to replace a previous La Crosse clock that served me well for many years. I specifically chose an atomic clock to avoid manually setting the time, particularly during daylight saving changes. For the first year, it worked as expected, automatically adjusting for daylight saving time while reliably connected in my bathroom, where it has been easy to see and convenient for everyday use. Recently, after changing the batteries for the second time—since I use rechargeables—the clock suddenly stopped connecting to the atomic signal. I tried multiple troubleshooting steps, including relocating it near an outside window to maximize its connection strength, but it still refused to sync. Despite having never needed to manually set it until now, the clock no longer updates, which defeats the purpose of an atomic clock entirely. To make matters worse, when I reached out to customer support for warranty service, I was greeted by an automated message about high call volumes and instructed to leave my contact information. I’m still waiting to hear back. Unless they replace this unit, my opinion stands—a one-star rating for a device with a disappointingly short lifespan. La Crosse has let me down with this model, and I’d recommend looking elsewhere if you want a truly reliable atomic clock.

No back light like I thought.

Easy to set up, great size

Easy to read across the room. Accurate time and easy to set up.

Difficult to set, can’t get daylight savings time into the system

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