I used to use this consistently a few years ago as it's affordable and does a pretty good job. Nowdays I only purchase this when I've run out of my Napoleon foundation and can't make a trip to Auckland to get any more.
Revlon colourstay has a good coverage, esp if you suffer from red veiny cheeks as I do and is very easy to apply, with either fingers, a sponge or a brush. They have a good colour range too.
The main reason I stopped using daily was I found it was rubbing off during the day around my chin and tip of my nose and I just don't have the time for touch ups during the day.
It's a good all rounder foundation, esp for those just starting out. I like that it has a fairly matte finish, as I'm not into the dewy look at all.
I use this foundation everyday and love it. The colour selection is fantastic. 150 buff is the perfect shade for my skin as unlike my other foundations it is not so much yellow based, nor red based... just natural brown skin colour. It gives me good coverage for everyday and is dirt cheap. I buy mine of Trademe for $18. Only con is it does not come with a pump unless you buy instore for double the price. This means I have to clean it off the back of my hand after application. It feels nice on my dry skin and does not go cakey on dry areas.
Tips: It does feel sticky after application so you must alway use a powder on top.
