The Naughty Ruler from Ruff doggie styles really is a basic ruler with a handle, but it does include other features. It lacks a metal piece like many rulers have, is thicker for impact use, and is also wider to cover more area. These improvements make it a great purchase for BDSM play for beginners or advanced users.
Decent review, but please work on your cameraman, I was a little dizzy halfway through! Keep up the good work! :)
