So, today I received my VV Gripper, and as soon as I inserted the battery, the display lit up and stayed lit. It works properly as far as displaying the numbers, and the numbers disappear when they should, but the light stays on no matter what. Even if I do the 5 clicks and the display says "off", the light stays on. I don't think that's how it's supposed to work. Is this a setting that I can adjust, or do I have a buggy device?
