Works very well, I like the active/working green light showing it as on/active Adding a marketing marker afterwards, think the cheapest low quality led flashlight possible but still it comes in handy more than once so yes it can throw some light when needed so I think it's proof everything is very good sensitive and it's 0 had wrong readings compared to a more expensive yellow brand that misread several times and gave me minor electric shocks, this is the one i go to to confirm iv has tripped the correct switch.
