Genuine long lasting foundation that's quick and easy to apply?

[Thurlow]

Can anyone recommend a really good foundation that does last at least 12 hours? I've seen lots of mentions of Revlon's Colourstay but I'd prefer something I can just slap on very quickly, and all the reviews of Colourstay I've seen suggest you have to be quite careful how you apply it as it dries quickly.

Smashbox 15 hour one is good and easy to apply- don't use too much, good coverage and lasts

I bought the 25 hour Rimel one yesterday based on this thread. I love it as it gives a fairly natural look when applied lightly -doesn't cake or look too matte and fake. It lasts a long time and hasn't dried out or irritated my dry, sensitive skin. Its going to be great to wear to work as it makes me look polished without being overdone. And even my DH has said it suits me (and not because its a lot cheaper than what I usually buy as he has no clue what different cosmetics cost!).
