The most useless thing I have ever bought! 1) It stays on for only a few seconds and then you have to touch it to turn it back on. 2) It has excessive - annoying brightness, which cannot be adjusted! 3) It requires three whole batteries to work, which run out very quickly! 4) It does not keep the time in memory, so if you change the batteries, you will have to ...reset it from the beginning!!! 5) For the settings, it has only three buttons, so adjusting it is a real torture! 6) To manage to set the alarm, you need to have a master's degree or pray to Saint Paisios!!! 7) Its dark gray color is due to cheap plastic that they stuck on a light-colored surface and it chips at the corners with the slightest bump!!!
