Love it. Since the oil filter is on top, changing the oil is a snap. I was beginning to hate the thing last weekend, after doing all four cars, but that's pretty rare.
It seems to be holding up very well, despite servicing a "fleet" of MB cars.
I still remove the pan and crawl around under the car every 15,000 kilometers to check stuff out, but I still use the LiquiVac.
Best $75CDN I've spent in a while.
