To turn on an Eye Force, you press the button and it "stands up". To turn it off, you press it in. The problem I have is that it doen't want to reliably turn on... button won't come out. Is this a known problem, or am I missing something?
I figured this out last night. It was because the battery door on the bottom was screwed on too tight. After giving it a little relief, it worked fine. Not manufactured to the tightest tolerances I guess
