Review: A Top Product and Useful At Night - I bought this 5 years ago and it's been pretty much on constantly since then. The red projection looks bright and is easy to read at night or even during the day. I have mine projecting on the ceiling over my bed so I just need to look up to check the time. It's not so bright that you would be awoken by it and the main clock panel also has a dimmable light (I keep it on the lowest setting most of the time.) The clock does take batteries but will only use that to run the clock during power outages (not the projection clock). After 5 years, the red LED is showing some wear but the numbers are still pretty easy to read. I prefer to secure my main clock to my nightstand with velcro and it works well to keep it from sliding. The outdoor unit is easily mounted and the batteries (I use Alkaline) last for months at a time (at least 10 months). You can mount it high under an eave or porch roof to keep the water out. Note that I did not review the alarms because I do not use them. Having the time, weather, and humidity readily available on the ceiling has saved me countless hours of frustration at waking up when it's dark and not having to get a face full of cell phone display or turn on a light to see a clock. I am not sure if this unit will last for decades but, for the money I paid and the convenience I get, it's well worth the cost.
Review: Nice clock - I enjoy projection clocks very much. This one works very well. Very intuitive to set up and keeps excellent time. The projection is well focused and a great size, very easy to read in the dead of night. I would for sure buy this one again.

## Questions & Answers

**Q: could I send the remote to the north pole and watch climate change and global warming with my brother?**
A: Santa.... is that you???

If you manage to figure out what's kind of wireless frequency this device runs on, you can then make a few thousand signal repeaters (much like a wifi repeater or mesh networking) leading from your living room to the north pole, ensuring to keep the repeaters less than 150' apart (as the advertised 200' is best case scenario, like an amplifier's RMS rating) for optional signal transmission. Yeah, it would totally work. I will have to warn you that latency will be a nightmare as this is a home product and your repeaters will be shoddily made. You'll most likely know what the conditions were in the North Pole 3 weeks ago. Stick to NOAA or The Weather Channel for more up to date conditions. (Totally not trolling)

**Q: is there a radio in this clock?**
A: THERE IS NO RADIO ON THIS CLOCK

**Q: Can 2 of these sc91 stations be connected to the same 3 wireless transmitters? i have 3 outside sensors and want to monitor them from 2 rooms.**
A: I believe you can if they are the same manufacturer and on the same channel. I have used one transmitter for two receivers in the past.

**Q: how do I set the time?  when daylight saving time started my clock did not adjust itself**
A: Please note that this clock is not atomic clock, the time needs to be set manually. To set the time, please long press SET button to enter the time setting.

### ⭐⭐⭐⭐⭐ A Top Product and Useful At Night

### ⭐⭐⭐⭐ It's a good clock, and the temperature data is accurate, but...
*by W***L on October 7, 2022*

The SmartRO Projection Alarm Clock w/Weather Station is a nice clock and the instructions are easy enough to be able to set it up in ten minutes. The display has 4 levels of brightness (super bright, bright, night time, and off) which are very useful, although I don't really ever use the "super bright" level as I feel the "bright" level is adequate enough. The projection of time and temperature is crystal-clear on the ceiling and since it's red, it doesn't interfere with sleeping - at least for me. Now, the Weather "Prediction" part (Upper right corner) is something of unremarkable quality. I placed the outside sensor under the roof on an outside patio area where it is safe from rain-intrusion, but it can accurately measure the temperature. They claim in the instructions, that after a few days of being able to sample the outside temperature & humidity, it will "accurately" predict the weather ahead... I find this to be a tad amusing, as it was unable to predict rain twice since I've owned it. That said, for the price with a single outside remote sensor, I think it's a good value, and will probably buy one to give as a gift to a family member.
