Does any one know if it's not good to hang your guitar by the nut area?

I bought one of these wall hangers and i don't know if is recommendable to hang a heavy guitar (a les paul) like that.

I've seen them hanging like that all teh time in stores like guitar center, but i wonder if someone has had a bed experience with it, meaning if the neck will get damaged or something.
