I am a huge MAC fan and used Studio Fix for years.
The packaging is simple and classic as most MAC products are. To get to the product you have to unscrew the lid and get your brush in there. It can be quite hard to get the last bit out of the bottom when there isn't much left.
This product applies well, a little seems to go a long way and you can easily build up. It provides a really good medium level coverage and leaves your skin looking velvety and matte. It lasts well - basically the whole day for me.
I find this foundation to be a bit drying, so would be hesitant to use this in winter when my skin is crazy dry.
Ive really enjoyed the quality of Mac foundation, the only thing that annoyed me was the need to set it with a powder but I guess 99% of the time that is normal :)
