Query: Completely Unreliable

I do agree that this alarm clock has many features, like an AM/FM tuner, a double alarm, and a bright display.But it is very unreliable with its alarms. It did work fine in the 9 months I owned it; then things started to happen.Five months - The radio quality seem to drop A LOT! Many stations refused to come in, and it made it almost unusable.Six months - The bright display was much darker when I first bought it. I had a hard time reading the time due to this.Nine months (THE FINAL STRAW) - The alarm would not go off at some times. In a month, six alarms did not go off, and I was way behind my day. And to make matters worse, the alarm would go off at random times; in one time it went off at 1:00 AM, and that was awful.It has a few nice features, but it's not durable. Unrecommended.
