Anything helps to reduce risk. A buzzer is a smart thing.

As a pilot I do watch gauges, but you'll find many extra warning devices on a plane too. You don't just rely on your checklist either. You're supposed to watch your airspeed, but there's a nice stall horn just to remind you. Sometimes you get busy in the seat.
