The volume function is great! There are times when people are still sleeping early in the morning when we cook and that soft alarm volume is nice. The louder volume can cut through the noise of our busy household. It came to me switched to the softer volume. With my older eyes, it's a bit hard for me to see the symbols for the volume. I just know now that switched down, it's softer, and if the switch is upward, it's in the higher volume.
Very happy with my new Cooking timer. I checked and the timer does keep excellent timing. The three small magnets on the back cling tight to my microwave where I have it stationed. It does wiggle a bit when you set the time, but will not come off.
