Should I remove this directive from web.config?

In order to see exactly what error was occurring (I was only seeing a generic err msg), I added this to my web.config:

<customErrors mode="Off"/>

That did the trick, and I was able to quickly solve the problem. Should I now remove it, though, so that users won't see specific info about my site's "innards"?

 

It is a good idea to only turn that on when you need it.
