If only there was a similar feature on filters. The only time I get any drips of oil on me are when I pull the bloody filter off. Yeah, I've tried punching a hole in it with a screwdriver first, but then there's oil on the outside of the filter when I go to twist it off.
I love the fumoto though. Only disappointment is that you don't get the benefit until the SECOND change after you buy it. It was a bit of a letdown to shell out the bucks for a fancy drain valve, and then STILL have to drain the oil the old way one last time. From then on - never regretted it.
