Have these at dollar store too, but this one seems a little more heavy duty with a good ringer and easy use to start/stop,

Great and work well

good quality as always

I've been using it daily to time seeping time for tea. It's a tad loud, but not enough to give a heart attack

Good kitchen tool

This works very well. The alarm is quite loud for the size & it has a clip and a magnet on the clip - you can stick it on the fridge or clip it on your clothes.
