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

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.

This time-temp clock is great. Easy to set up and use and projects a clear image on the ceiling that's really easy to see at night. And the red light doesn't add unwanted light to the room

Nice features with fairly easy setup. Display is nicely laid out but rather bright at night, but I don’t mind it. It’s nice to see time and temp at one glance. The power cord is rather short compared to my last model. Another foot would be perfect. It replaced a LaCrosse unit that never seemed to adjust the daylight savings automatically. This is easier. Not planning to use the alarm clock feature but it has 2 available.

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 is worth the money. I've bought 2 now, the first was for my father and after seeing how much he liked it I got myself one. The screen brightness is easily adjustable and so is the temperature conversion(too easy). Its a great size, I only wish the angle could be agdjusted on the physical clock itself and not just the red projected time.

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!!

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!

This is my third projection clock. The clocks last forever, the outside guages not so much. Cincing them up is usually a nightmare. This one was easy peasy. Gorgeous screen display. Ceiling Projection is clear (could have been a tad larger, but easy to see w/o my glasses). Just a pleasure to set up and set time etc.

Très bon rapport qualité prix

The station of temperature and humidity outside the house and inside the house works with high efficiency .. especially there is a possibility to monitor it in more than one place and also display it on the screen or on the wall or ceiling in perfect clarity ... wonderful and excellent equipment

Very good product

La sveglia a proiezione funziona bene e sono soddisfatto, la regolazione della retro illuminazione del display è perfetta, si può scegliere tra più scale fino allo spegnimento, peccato che per la proiezione c'è solo una regolazione, o minima (stanza buia "illuminazione insufficiente") o max buona illuminazione (troppo per la notte, ma sufficiente per il giorno). Se c'era una posizione intermedia tra la minima e la massima era perfetto. Comunque la consiglio.

Me gustó que la proyección por la noche es muy fuerte y clara. Con luz regular natural sin abrir las ventanas a eso de las 7:30a.m. aún se ve en el techo.
