have this alarm non for about 3 months. who at the beginning of all great but now :( The major flaws: - Improvement software crashes constantly. - Wakes not reliable! Sometimes he does not go times :( - After Softwareabsturzt constantly, the battery must be removed to start in again. - The display is easy to read only a few positions. - Sometimes finds a radio signal - after absturzt the software. - Reaching the alarm leads increasingly to Softwareabsturzt.
