I really like this clock. The screen image is easy to read and attractive. Nice sized 1.5 inch clock digits. The temperature readout is accurate and cool to know. I appreciate the many levels of dimming and brightness, I think there are 6 or 7 levels. I took photos at its brightest setting and dimmest. At its brightest setting the digits look almost white, very light blue though. At its dimmest setting the digits look slightly more blue, but at its dimmest the readout is almost hard to see, yes, it is THAT dim which might be a good setting for a dark bedroom but certainly not daylight conditions. My clock had the correct date and time right out of the box. But make no mistake, the clock is set at the factory and remembers the time while disconnected from power with the button cell battery that is installed in the interior. It is not getting the time/date by radio waves or anything. I always set mine according to the NST time anyhow. After setting mine it has kept very good time for the past few weeks. It automatically changed on March 10 for the daylight saving time change. I was waiting for the time change before writing this review. Not many clocks out there show date, day, and time plus inside temperature PLUS are capable of automatically adjusting for daylight savings and back. This clock has all of those features working correctly! I don’t use the alarm feature so not rating on that. But overall the display is nice to look at and full of information without going overboard on information. Nice.
This is exactly what I wanted and needed. Plug it in and it sets itself. The color is a soft blue led. The pictures I’ve posted don’t do this clock justice. It is very gentle on the eyes and has 5 dimmer settings plus an automatic light setting for the led. I love the ease of this clock. I haven’t used the alarm function yet, as I use my cell or wake up naturally. This clock is great! I’m going to buy another one for a desk downstairs.
I spent way too much time looking for replacement bedside clocks for my wife and me. The ones we had failed in a number of ways, and I didn’t want to repeat my mistake. This DreamSky clock is really perfect. The display is very clear and very comfortable on the eyes. I have it dimmed to about 40% brightness, and it is very readable in daylight without any glare on my eyes.
I live in the Eastern time zone, so as soon as I put in the 3 AA batteries and plugged it in, it had the exact time, day, and date displayed. All I had to do was adjust the alarm (preset to 7 am) and the brightness of the display (just push the – or + buttons in normal time mode).
I did add one of those 90-degree-angle plug adapters to my outlet, so that the power supply would sit vertically in the wall socket because it would stick out into the room too far if plugged straight into the socket (along with the added length of the USB plug— my outlet is behind bedroom furniture that sits close to the wall).
