The price may seem daunting, but it is really worth it.
The build quality is good, the course manual and in several languages (including German)
although the operation of the alarm is very intuitive and actually needs no instructions.
As incredible as loud as the alarm is displayed on the Internet, I feel the alarm not - but this should not mean that in heaven's name he would not be loud enough).
The vibrator function is the real highlight. Set reasonable and cable from under the pillow - awakens guaranteed! However, if you only use a pillow you can feel the device already.
An additional plus is that the alarm clock is designed for battery operation - not only good to sleep through for holidays, but also if you have ever had the experience because there was a power outage at night and then the alarm clock did not ring!
All in all, worth buying in my opinion, definitely.
