Easy...Easy...As for advertising, leave it alone. I am sure if I gave these guys (see, I didn't even mention their name) any free advertising, it was likely worth what was paid, zero.
As for drilling, yes, I am a man with a drill, even a saw. But, I would like to do it simple with something in the drain before cutting.
Also, has anyone tried this one? It is $59. Seems too cheap but would like to know:

...and, no this still is not advertising. In fact, I believe I have now listed two different companies, likely competitors.
