6s oil drain plug
 

So, something bad happened to my oil pan plug when I changed it last (the head of the bolt was stripping like it was made of lead). Basically, I want to replace it with one of those plug drains (the kind that you don't have to unscrew evertime). Some can be found here: http://www.quickoildrainvalve.com/.

What I wanted to know was A) has anyone had any good or bad adventures with it? and B) What size is the drain plug for a 2006 6s again? I think it's 15 or 16 mm, but I forget.
