I work 12hours shifts and always found my concealer never held up to the long hours. I bought this and love the fact that I have found a concealer that lasts. One thing I will remember when purchasing again is to get a lighter shade. I bought it in the same shade as my old concealer, however this has almost a yellow based to it (not a fan). I know I will continue using it, but I do feel it is a concealer you have to get used too. PROS longlasting, covers well, you only need a tiny bit so depsite the cost it lasts a long time. CONS bit of a color change, doesnt blend well (I apply it when my primer/moisturizer has not quite dried for easier blending), the pump is awful (Mac should consider changing this).
