Good points:Large displayUses one AAA battery rather than a button cellHas an on-off switch (but see below)Simple operation using three buttonsCan be used as a count-up or count-down timerLoud enough to hear from the next roomNice strong magnet to mount on refrigerator or stoveBuilt-in flip-up stand, and loop for hanging or lanyardMaybe not so good:The on-off switch is not the most robust feeling, but seems to work well enoughNo automatic shut-off (probably because it has a switch)Some people might find the alarm annoyingly loudColors aren't subtle -- light blue and green, with orange buttonsFor the money, nice functional timers that work well and are really handy.
