I know how, but I'm worried about a cross between not winding it at all and over-winding it.

When I brought it, I was shown how to wind it and told to do such everyday. The seller demonstrated until he hit an invisible barrier. I've only been able to wind it once since buying it, I've been coming back to it every day since and not being able to wind it up any further.

Am I supposed to wait more than one day? It's been a week (7 days) since I've brought it. I'm confused. Please help, and thank you in advance! .

I have --no-- idea where to put this question, sorry.
