Nifty, but is it really that hard to change your oil? Plus I wouldn't know how effective this is. All it does is siphon it out the same way as if you used your mouth on a hose.

Pretty expensive for bits of plastic too.

I own the 3 qt model and must say it works quite well for diffs and lawn mowers, etc. Haven't tried it on the car, its much easier to just take the drain plug out.
