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

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. Read more

Nice clock. Clear display, easy to set up. Love the overhead projection - in fact, we leave the face display off to keep the bedroom dark and only use the projection at night. Had our first clock for years, this is our second purchase. Read more

It’s an okay product it works okay I did have a issue with the projector it just wasn’t working and suddenly it started working again I like the projector on the ceiling which is why I purchased it but I think it is kinda pricey for what it is it is smaller than I thought it would be the display is easiest to view from straight on nice color display but again it is small Read more

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. Read more

I normally never write these but I have had this clock for 3 years and it has been the best clock I have ever had in my entire life. I work outdoors and the sensor for temperature sets me up perfectly for my job and hobby’s. Read more

Lots of detailed information nicely designed. Bright and clear information on overhead display. Included battery backup is appreciated. Read more

The projection feature is good, however the screen goes blank periodically, unknown as to why. The battery back up does not work. Each time the power goes out, the clock has to be reset. Display size could be a bit larger, and the orange is hard to read. Otherwise works good. Mostly satisfied with purchase, although there is room for improvements! Read more

Seems to work fine I put batteries in the outside unit about 6 months ago and it's still sending signals. I always wanted one of these and I am glad I got it. I wouldn't really rely on the weather station part of it since it's not that accurate but it's still a nice clock Read more
