SMARTRO SC91 Projection Alarm Clock for Bedrooms with Weather Station, Wireless Indoor Outdoor Thermometer, Temperature Humidity Monitor Gauge Hygrometer

My beloved used to wake me up at all hours of the night. He didn't know what time it was - It happens less often now and even when it does I can easily glance at the ceiling and let him know when he can wake me again! So grateful for this clock and we love the feature of the temperature in the room we are in and the one that we put in another room outside our room. So helpful!

CONS: Base and 3 remotes give different readings when placed side by side with a temp difference of 2.1 degrees highest to lowest. The remotes have a little molded "kickstand" that make it difficult to mount to a wall even when using the screw hole on back of remote. The seconds blinking on the base can be detected when the base is on its lowest light setting making the room blink.PROS: The base is simple to set up and it has a very easy to read display. The celling projector is bright enough to be easily seen, not too bright to light up the room. The directions are clear enough to not require more than a once through. The time is very simple to set up. Easily replaceable batteries in the remotes.The pros outweigh the cons.

I wouldn't say that it's defective exactly; It works, and as advertised. It's just very hard to read unless looking straight at it. This is a common flaw with LCD displays.Has day and date.12/24, good. The display showing it's in 24 hour mode isn't necessary.Buttons are on the top, not back like I've seen some, good. Big snooze button, good. Button functions are a bit confusing.Projector is cool, but weak, even at 8 feet. Needs 90 degree rotation as well as 180.The weather display is kind of meaningless; Based on internal projections based on temperature and humidity trends.Has external wireless sensor but range is limited. You'd expect this, as by definition the signal must pass through a wall.

These interior/exterior Projection Alarm Clock/Thermometers have a very clear display on house ceilings, with a sequential display of times/temperatures, alternating between interior and exterior temperatures on ceilings. My house has very high (13 foot) ceilings and the ceiling displays are very bright and well-focused at night. During the day, you must look at the colorful 4.5 inch LCD display on the base unit, as there is too much light to see the alternating display on the ceiling. The LCD display is identical to the photos shown in the Amazon description, with a constant display of time, interior and exterior temperatures, and interior and exterior humidity (shown in percentages).The small battery powered sensors are powered by two AA alkaline batteries and last well over a year before requiring replacement. These sensors also have a small LCD digital display that continuously shows the temperature and humidity. In my experience, the sensors have a good radio frequency range of at least a hundred and fifty feet and can penetrate multiple walls and several floors in my large Victorian house.Initial set up on the SC91 is extremely easy, as is battery replacement, with no settings lost during battery replacement. Each base unit and sensor can be individual to one of three radio frequencies. I have two units and two sensors operating on two different frequencies without difficulty or interference with each other. Reliability appears to be excellent, as I have had one of my systems operating continuously for 18 months, with no dropouts and no display degradations over time. Highly recommended!!!

I really liked this projection clock. It displays much information about humidity and weather forecast by the barometric pressure. Very colorful and easy to set up. It did take some getting use to as the ceiling display seemed a bit squished and hard to read right away. But after a few nights I found the display easier to read.

This projection clock shows inside and outside temperature with a remote temperature reader. Looks well made and sturdy. Will buy again.

Oh this was really disappointing truly. It is basically perfect in terms of features and what information it shows. Unfortunately it has one major an crippling flaw, the damn screen and font size is way too small.Unless it's for your desk where it's close up sure or for next to your bed at night. Otherwise it's way too small. In the dark the projection on the ceiling or wall is hit or miss if your in a pitch black room or not but still the projection isn't stron enough a and doesn't display everything. If you have vision issues this is even worse. I had to return mine and get another one which although has bigger text it still is too small.The pros Is all the information it gives and the seperate room temperature sensor.In conclusion this would be the perfect digital clock from every metric if the screen and text was 3 to 4 times larger and the light projection was also bigger and thicker/bolder.

Great, bright easy to read just as advertised although instructions aren't very clear
