Pros
Small and convenient
Main display illumination can be turned off
Projection is bright - though not bright enough to disturb me as I sleep
Uses 2 AA batteries for time backup

Cons
24 hour setting does not have leading zero for midnight to ten AM - Should display as 02:00 not 2:00
When projection is reversed the temperature is shown above the time - should be below or optionally be able to be turned off
Projection brightness not settable - may be to bright for some

Only use it as a clock in bedroom. Have separate alarm clock. Replaced another projection clock that had failed after three years.

Did take a few days to acquire the signal to set the time.

Love the large, bright display on both the face of the clock and the ceiling projection. Wish I had gotten the one with the outside temperature or day/date instead. Our home is almost always climate controlled (heat & A/C - rarely open windows) so the room temperature only fluctuates a degree or two, depending on the severity of the weather. The other features would have been more useful. I'm still very happy with the display and projection, they are far superior to a previous clock that we couldn't see with lights on or in the day time.

This clock/radio is very small. The projection light is strong and visible at night on a wall 12 ft away. The radio works well. The 2 reasons for only 4-stars is that A) the small size requires you to hold onto the clock itself when you want to change the radio station or adjust the volume. If you don't hold onto the clock you end up pushing it around when you try to use a button, and B) the projection only flips 180 degrees, that means if you place the radio on your nightstand and face it towards you on the bed the projected numbers are sideways on the ceiling. So for this to work for me I projected all the way across the room to the opposite wall. It works and the numbers are very visible at night, so overall the clock/radio does what it is supposed to do.

It wasn't what I thought it was, I had misread and thought it was Radio also. But I have come to like it, and it does everything it says it does on the Advert. It was basically Plug and Play, I didn't even have to set anything except for the Alarm. And Now I have a clock that works with out needing plug. I will see how long it runs on just batteries, but for now it's in my Computer room, so when I play Diablo, I have clock I can keep track of time with. Very compact and dead on the money with time.

It does what it needs to do. Projection works fine, but can be frustrating to find a place you can set it where it can still be read during daylight or with lights on, which I suppose should be expected - even high-powered projectors struggle with bright ambient light.

The display is one of the weaker elements of the product. It works, but would have benefited from using the older alarm clock style of "glowing numbers/letters" instead of the unlit characters and orange backlight. If you look at it from a less-than-perfect angle, you can't read the display. Not ideal! It will also obnoxiously blink the battery indicator perpetually if you do not insert the three AAA batteries, which is unnecessary given it comes with the A/C adapter and you would only need the batteries for perhaps battery backup or to use the radio and clock portably, sacrificing the majority of the projector's purpose as battery power only powers the projector and backlighting for a couple seconds when pressing the snooze button.

Built-in functions work without any issue I've discovered. The time auto-set takes a bit to work, so you'll need patience. All the controls work, though for seemingly no reason the power button requires you to hold it down to toggle radio power instead of being a simple button press as you would expect. The manual gives no reasoning for this, just calling out that you need to hold it down. AM/FM band switch takes a second or two to switch the function. You get 4 radio presets per band (though the manual erroneously states there are 5), which is a very nice touch given many non-vehicle radios lack preset options. Tuning is digital and offers both fine-tuning (FM dial allows tuning by 1/20 of a MHz) and seek functionality. Volume goes up to a pretty loud for the device level of 20. Features both a buzzer alarm and a radio alarm. FM reception comes with an external wire antenna rather than some cheaper devices' tendency to use the power cord for antenna reception, while AM reception uses the common internal antenna that requires you to rotate the device to adjust reception, which is a problem here because that means your projector gets moved as well. Not as much of an issue if your projection target is straight up.

The biggest weakness is the speaker. While certainly alarm clocks are not meant to be stereo replacements, there is a point where a speaker is probably too small. The speaker in this device is roughly the size of a quarter, and easily gets "blown out" (as in introduces distortion, not the form of "blown out" where speakers cease to work) well within the volume range the device provides. AM radio band gets this more easily due to the EQ and frequencies used there, with distortion at as low as volume level 12/20 on talk radio. In contrast, an old GE clock radio I own has a speaker closer to the diameter of a drinking glass coaster and offers much higher audio fidelity without a blown-out sound. I recall seeing small speakers like the one in this product in cheap products that used the speaker for a buzzer at most. For what it is, an alarm clock that offers radio playback, it's sufficient, and no alarm clock is meant to be a stereo replacement anyway.
