Love This!

JoJune 19, 2024

This clock is very nice. Brightness can be adjusted quickly, projects nicely, small and easy to manipulate. If there was a complaint, my only one is is that because it is lightweight it falls over on my doily easily. Otherwise, well made, works great and shines on my ceiling brightly to see easily without glasses! Yes I would purchase again! Read more

Great projection !!

RobAugust 18, 2025

Awesome little clock. I love the fact that the screen dims down and not bright at night. And the projection it clear and bright on the ceiling. The charger works great and a simple set up. Read more

Still New But Seems to Do The Job, Mostly

J_SnellJanuary 4, 2024

Ok, so it's a clock, it's small, it was highly rated, it was on sale, and it's supposed to tell time and project it onto the wall/ceiling, in a purely basic sense, it checks all the boxes for me. GF and I got "spoiled" by the projector clock I have in my bedroom and have both made the comment, "we need one of those projector clocks for when we travel, so we can look up in the hotel room and see what time it is in the middle of the night". My room clock is a whole nightmare to set, so it's staying put. This little clock does what we said we wanted, reasonably well, however, the button to rotate the projected angle, 90 degrees at a time, that button does nothing on mine, yes even when plugged into AC power. I'm assuming the button is defective, but it's so minor, and the clock is for travel only, so I'm going to just deal with it. Read more

This is the perfect compact projection alarm clock for the bedroom!

tx1200February 7, 2024

What I like: - The red projected numbers are bright and easy to read even with a tall ceiling. I was looking specifically for red projection to reduce blue light at night known to disturb sleep and disrupt melatonin production. - The projection feature can be reversed if you want the numbers behind the clock. - The front display is adjustable from very bright to dark at night. It is also easy to read. - The clock function is very easy to set up. You don't need a big book of instructions. - The added functionality of a USB fast phone charger is a welcome feature. - The clock unit is small taking very little tabletop space. It's somewhere between a pack of playing cards and a cell phone in size. What I don't like: - The clock is very lightweight and easy to move out of position when connecting the phone charger. I have to adjust the clock position each night. I'm thinking about velcro to hold it in place. The bottom line for me is that it wasn't expensive and worked exactly as I wanted. That seems to be rare these days. Read more

Excellent device!

Nyoka HolmesDecember 5, 2025

UPDATE; I actually found the problem and it was not the clock. The wall plug was not installed correctly in this new apartment. The clock is well worth it. The projection light won’t stay on. It comes on then immediately goes back off. Read more

Intuitive, light, travel, friendly

CarissaJune 13, 2025

This clock was exactly what I was looking for. It can assess internal temperature and humidity you can set it up to go with the clocks. There is a space for a battery so that you don’t have it plugged in all the time for back up power as well as for travel. It stores the time and date so a battery is a good idea if you’re wanting it to keep the time. It is accurate functional and exactly what I was looking for I love the little feature that the brightness is just tapping the top as well as the news feature. There are two separate alarm clocks you can turn on physically so you can physically tell whether or not they are on. The brightness is the same as the snooze button so you can turn the back light on the display completely off for those who do not want to have blue light at night. it’s simple easy to use and perfect for me. Also bonus I love the fact that you can change the direction that the projector is projecting. You can kind of move the little arm, but you can also tap a button on the back that will turn in four different ways the clock direction. This was not given to me by anyone I purchased it. And no one is paying me for this review nor did anyone direct me to this product I found it on my own. Man, it’s sad. We have to live in a world where you have to say that but, we do. Read more

easy setup, clear projection of time on ceiling

LG from TroyJanuary 6, 2025

Small, but very effective. Does not take much space on end table by bed but easy to see projection on ceiling day or night. Setup easy. Has USB port to charge other devices if needed. Comes with AC transformer as well. Price point is excellent. Read more

Pros and Cons

Mountain BikerNovember 30, 2022

This clock had everything that I was looking for, or so I thought. It has several nice features, especially for the price, but there are a couple of design flaws that can negate those features. Pros: The screen has several lighting settings, including having the light completely off. The temperature feature seems to be fairly accurate, and the unit is very compact, so it doesn't take up a lot of room on my night stand. The numbers on the screen are fairly large, so they are easily read. Cons: The biggest downfall to this clock is its instability. The bottom of the base is very small and the clock is somewhat top heavy, so with the least little movement, the clock falls over. Also, the electrical cord comes out of the clock near the bottom, so this adds more instability to it. Another con is the projection. The best way to describe the projection issue is that the color bleeds from the numbers, so there's a red circle around the time being projected (photo attached). It's also very bright and there is no way to adjust the projection lighting. It would be nice to be able to dim this feature because I believe this would help soften the bleeding of the light and it would make the projection easier to read. Read more
