Users View of Admin

I've got some users complaining that they do not have the same menu items as I do on my end as an Admin... I have a few plugins that check if system admin if not turn off menu items.

What I would like is someway to log out as admin and then login to there account to view the menu as they would see it or a plugin that allowed me to add a system testing user to each account so that I could login and see the admin from there point of view. (for security reasons this account should be turned off unless I'm actively using it or something..!?!?)

Thanks
