I like using this when there is several people in our household who do the dishes so it's nice to know if what's in the dishwasher is clean or dirty without sometimes guessing.  But this magnet can be somewhat difficult to switch or even take off as there isn't a lot of room to grab it.  So we end up not really using it just because of that.  I'm sure we could attach something to it that will make it easier to grab to turn or take off but haven't done it yet
