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.
Review: Great product with no parallel but sadly the outdoor temp sensor stopped working. (Edited) - Edited Review: 3 stars -> 5 stars Ok, so based on my original review below after 6y of owning the clock and buying a 2nd clock I was so surprised they sent me an email based on my review and sent me a replacement sensor. The new sensor paired immediately with the clock on Ch 1 and is also the newer model which has a small LCD display on it. Now this is just amazing service honestly. I mean, after so many years, they still supported me this way. I liked their product that this was my 2nd purchase of it. Now I'm going to go ahead and support them and have gotten a couple more folks to buy this product via desertcart simply because this sort of support is just amazing. The sensor is paired and now projecting the outdoor temp again on the night ceiling and I no longer have the "--" after months of this. I can't tell you how happy it makes me to have things that now work as intended and the little joy it gives you. Thank you SmartPro. Original Review: So I bought this product because honestly there is no other product that is equivalent to it. It can project indoor and outdoor temp (via a remote sensor) and it has multiple colors or turn it off for no glare at night and reversible projection display (red color only) and it works wonderfully. Sadly one day the outdoor sensor just randomly died and stopped functioning. This was after I bought this unit a 2nd time having used it before. The best part was the outdoor temp honestly. Also the main LCD display got all weird but as long as it projects I'm good with it. Still will likely buy it again for the 3rd time simply for the nice indoor + outdoor temp cycle and excellent wall projection of time. Very useful at night. Shockingly I don't see other products that can do this.

### ⭐⭐⭐⭐ Pretty good
*by L***S on August 1, 2026*

Very nice projector clock. Pretty small and light, and the projected image is fairly small, you better have good vision to read it. The outdoor sensor merely has a press-to-fit battery cover, would like to have it screwed in to keep the batteries dry
