Have added new batteries and seems to work but will be sold as seen and not tested (I don't know how to use it!). Screen has dust / dirt on the inside. Buttons are worn as seen. Can't work out how to turn it off. Off button doesn't do that..... No returns on this item please. Happy to follow any instructions to test it as needed. Requires 4 x AAA batteries not included
