For this device, I decided, since it has a very good price and the reviews were consistently good. The time adjusts automatically (which is not the case with many other manufacturers - for me but a decisive reason to buy), the projection can be tilted as desired - but only about an axis (see product photo). The time therefore can not rotate freely, but I did not clear before and it also goes really, ultimately, you can also turn the alarm clock so slightly. The projection is very easy to read at night, it is not flashy but just right. The projection shows described only the time and not disturbing circuit or the like as partially at Rezesionen to other devices. A small downside: the dots between hours and minutes blink that could have been omit - micht störts not, but others might. The display is very good ablesebar, from the side or from above. The buttons are easy to reach and the alarm clock can be operated, there were no problems easily. He is certainly not a design object, but in "real" it looks very good, feel and workmanship are very good. Can be in the unit also use batteries, it can operate without a power supply, but then without projection clock. Conclusion: great price, very good alarm clock, automatic time setting, good projection
