Got it in the mail a few days ago and decided to change my oil today since it was due. I searched the entire forum and didn't see any threads on it.
Fairly easy to use it, but I found I had to pump every 5-10min to keep the oil going. Think it took me 35-40min to fully drain it out.
Also believe I got all the oil out, logic behind that is I put back in 5.5litres of oil and the dip stick was showing between half and full. From what I've read on here our engine takes 5.5-6.0litres.
Why I like it
1. No mess
2. Easy to do
3. Don't have to lift the car or get under it at all
I have read on other forums that people dislike it for not getting all the oil out and others loving it for the reason's I posted above.
