Review: Fantastic Clock - I searched through MANY atomic clocks to find the right one. This one hit all bases in many ways. First the fonts are big enough to be seen. Most clocks sold are way too big in size and font and non aesthetically overbearing/obnoxious. Secondly most clocks of this ilk come with an outdoor sensor. Those sensors don't last and are cheap. The elements easily kill them. So basically you'll have one side of the clock not showing temp as the sensor is broken. Plus, it's much easier to use your phone to get outside temp. LOL. Third, so the outside temp is replaced with a humidity sensor which is much more useful to your immediate surrounding. Fourth, it's wood tone. So at least some aesthetic to the decor vs. the regular industrial looking black or silver clocks you see on desertcart. Lastly, it's consistently accurate to the second. It quickly grabbed the Atomic clock signal. And additionally, it has auto daylight saving time. No need to readjust during the DST switch. Plus it fully says the name of the day of the week instead of just a 2 letter abbreviation. AND the numbers are CLEAR. Nothing like some of the early photos here. It's is crystal clear LCD from all angles! So they must have improved the panel.
Review: Great looking clock and easy to setup! Love the display layout. - I bought one for the home office. Liked it so much that I ended up buying another for the master bathroom then another for the living room. The size of the clock can go just about anywhere and slim depth and the 3 available finishes make them attractive. They show the most important data that I desire with the hours and minutes being the largest making it very easy to read from the distance; even easy to see the time in the shower even with the glass enclosure steamed up. The day and the month spelled out are nice and makes it very clear and easy what day of the week it is. The temperature and humidity display are nice and with all of them together of all three clocks are less than a degree apart. The humidity is a bit different with one of them a few points in percent apart but for a clock that is good enough; it gives a good ballpark of what the humidity is in each room. The time is naturally spot on and I find them very sensitive that they get a full strength signal no matter where they are located in the house. I found them to be very easy to set up without using the instructions at all. Love this model of clock, who knows perhaps there will be more purchased in the future?
