The EZ change just looks cheap, but they may be fine. It is about $2.50 less for the EZ Change vs the Fumoto for me. But I do see the EZ Change uses an o-ring seal vs a washer on the Fumoto.
I have a Fumoto on my truck (drain hole threads are kind of messed up from a previous oil change before I got it, so the Fumoto keeps me from messing them up any more).
I have not gotten around to getting one for my Scion, but I have just started doing oil changes on it (had 3 years of "free" oil changes from Scion). Maybe I will try the EZ Change.
I know on my Elantra and Grand Caravan the amount of oil left in the pan was minimal (no more oil came out on the Elantra, and on the Grand Caravan only maybe 20 cc of oil came out, I pulled them off the first time I used them to check).
