Review: LOVE IT!! - Very satisfied!!! The projection time is large numbers clear and easy to read. I love that you can turn the projection on or off. No need for it to be on in the daylight. I love that you can choose the color of the light on the display and also you can completely turn the display light off. But at night all you have to do is touch the top and the light will come on for a few seconds and then shut back off, love that! Love the two separate alarm settings. Love that it has a USB port to charge my phone. And my absolute favorite part is IT HAS AN ACTUAL CORD THAT PLUGS IN TO THE OUTLET NOT JUST A USB ADAPTER WITH A CORD. Those USB adapters get hot when left plugged in 24/7 Great bonus that it gives you the outdoor and indoor temperature on the screen as well as on the projection! All in all, this is a great little alarm clock at a fair price!! Checked all my boxes Now, let’s hope it lasts for a long, long time? I had my other one that was a different brand for 20 years before the projection stopped working.

### ⭐⭐⭐⭐ THIS is the projection clock you need
*by C***N on November 12, 2025*

I purchased a different brand of projection clock that was so complicated to set up and use, we made the decision to replace it. We chose a different brand, the Smartro Digital Projection clock. It arrived quickly, was a breeze to set up and functions just as we had hoped.
