It comes with other benefits as well. Not even the cheapest alarm clock has ever failed me. Sure, it can run out of battery power but the low power icon shows up months before it runs out of juice. Phone alarms on the other hand? I had them not triggering at all, or the vibration motor in the phone being stuck (?) and thus not working temporarily, etc... Hence I also prefer physical alarm clocks without software that have one job and one job only.
