Product review (5 stars): great thing to stop grease fires
Stove top fire stop is a good way to make sure that you have some protection from fires due to renters or even myself being distracted from the kitchen.  It contains something like baking soda that is dropped directly on the fire once the mechanism is set off by the fire.  The two cans are magnetically attached to the hood over the stove top.  I cant emphasize how great these are.
