This product is SO easy to use! It now comes with the IPhone! Instant light source whenever you need it. (unless your battery is dead)
Pros - The light is very bright, you don't need to unlock your phone to use the Flashlight (just remember to shut it off) It's great for shining into small spaces, too.
It's a flashlight. Can not come up with any Cons with exception of it not working if your battery is dead, but that goes for any flashlight.
A must have for "Rainers especially if you are showing homes after dark or if the electricity has been turned off.
