Works to give me the status of lights for all my electronic devices.
I receive this the other week. I like it. I mainly got it for the light probe to tell me if lights are on and being it has a small area of view; I can move it around to find out what light is on in my house when sighted people leave them on when they come over. I also use it to tell when my spair phone batteries are charged or not. I also use it for my computer when I'm not getting any screen reader response and can't tell if the computer is locked up or is the screen reader just needing to be restarted. I basically check to see if there is any hard drive activity by checking to see if the light for the hard drive is flashing or not. If it isn't flashing; then the computer is locked up. I also use it to tell if my alarm is on for my intercom and other devices that have a power light when they are turned on or that have status lights when that function is on. As an example a fan that has lights to show if it is to be on for 2, 4 , 8 hours.
