It's ok but what can you expect from a basic K2 meter? I would only recommend it if you use it at night or in your house, but to be honest I would definitely never use it in my house lol π. I've done a lot of ghost hunting, so I'm sure someone will follow me home. The only issue I have with this K2 meter is that you have to be in the shade to see the lights and there isn't a tone I don't like. I like listening to sound on some devices, this is just the basic one so I will update soon.
