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

This clock is just the right size for your bedside table. It's awesome the way you can display the time and temperature indoors and outdoors on your ceiling or wall. You can set the clock for three different brightnesses. It displays the time date day of the week and temperatures inside and out plus many other things. It has a great alarm system. It is easy to set up just follow the instructions. I would highly recommend this clock.

This Alarm Clock is great. Time, inside and out temp projection, plus weather and the option for three temp sensors. Also has humidity and temp direction. Fantastic Alarm Clock for a Fantastic price. Had a minor issue with a sensor but this issue was handled immediately. Fantastic customer service!!

I've had this for 1 year now. It arrived with a dead pixel so there is a small black spot in the first digit. Certainly not a deal breaker but it is a flaw and one that is mentioned in other reviews and they address it in their description. The outdoor component goes off line and reports _ _ _ _ _ _ at least once a month. It comes back on it's own. Receintly, it was displying outdoor temps about 40 - 60 higher than actual temp and I have not moved the transmitter. Today it was only 5degrees higher than actual. The battery in the outdoor transmitter lasts forever, I have not replaced it in the year I have had it. The weather is not an actual forecast but a prediction based on humidity and activity.

Great clock! Projection is phenomenal! Very clear and adjustable. Looks sleek, very functional and easy to set up.

Nice clock if you're looking for a ceiling display. The ceiling display will show TIME on top with TEMP below. The TEMP will alternate between Indoor and Outdoor every 5 secs. That's if you have ONE outdoor sensor. It supports up to 3 and you select 1, 2, 3, or all. If you select ALL, the ceiling display will cycle through all three, meaning that if you only have two sensors, the third Outdoor Temp will be blank. I only have one outdoor sensor, so I selected #1. It comes with only one. Bright display, and easy to program clock. Only negative was that manual claimed it would take up to 3 minutes to link outdoor sensor and clock. I gave up after several 5 minute attempts and just left in frustration thinking I would send it back. The primary reason I purchased was to see Outdoor Temp in middle of night. When I came back an hour later it was linked and has worked superbly for last two days. Recommended if you can be patient waiting for Outdoor sensor to link.

I wanted an atomic clock, which this one is not. But I like it anyway, it is easy to set up and it has an outdoor temperature sensor, so it display both indoor and outdoor temps. I also like the ceiling projection, which show the time and indoor/outdoor temps.

This review is for the Smartro Time and Temp Projection Alarm Clock. SC91 Nice, small, compact, lightweight device. The internal battery is the small, round, lithium type. I like the internal and external temperatures. The brightness controls are good, so it won't keep you up at night. I'm not sure how the weather indicator is supposed to work. You set it to the current weather, and it magically adjusts? Based on humidity level changes, I guess. How does it know if it is cloudy? More of a gimmick, I feel. A lot of detail to cram into a 4 inch diameter screen. The overhead display is nice, but doesn't rotate 360 degrees, so if it facing your bed (on your nightstand), the overhead is sideways. Not a deal breaker for me at all - still easy to read the way it is, but if you want it directly over your head at night, you'll need it at the foot of your bed, for example. The biggest issue is the inside temperature unit is reading 10 degrees (F) lower than it should be. The outside device is fairly accurate, according to another thermometer. Humidity levels seem accurate enough. See image showing outside unit sitting next to inside unit and note differeces I contacted the company's support regarding the temperature differences. Lets see what they say. I'll be returning this unit. I'd keep it if it was accurate. No reason to live with a new item with the temperature 10 degrees off. One or two would be acceptable, as that is pretty standard for inexpensive weather gauges. Note - Amazon sent me a unit someone obviously returned (Not MFG's fault). The internal battery was activated (and working, saving previous owner's data, including the 6 AM alarm that went off when I didn't expect it to). I assume it was returned for the same reason I'll be returning this unit. What a waste of my time. Update - Contacted MFG support. They stated they are sending me another device. Very responsive. Review update - the periodic synchronization between the outside unit and main device is very bright. Actually wakes me up at night. I covered it. Otherwise happy!

The display is easy to see and easily adjusted to our angled ceiling. I love that we can see the outside and inside temps. We are very happy with this purchase.
