I've posted before about how much i dislike the 1.6, so I'll just copy and paste:
I have the MAC 1.6 case and I have not been happy with it. I bought it because it's insulated and durable, two qualities most other cases i've tried dont seem to have. The case is super-heavy; it really hurts to try to carry it, whether by hand or on my shoulder.
It doesnt really hold all that much; i can fit the same amount into the mac carryall, which is lighter, and convenient. I dont have that large of a collection, 2 x15 eyeshadow palettes, blush palette, 5 quads, a handful of paints, a dozen liners, a dozen lipsticks, few mascaras, a few foundations and powders, and that sucker is FULL. I thought i was moving up from the carry all to a lot of room, but not so much.
The thing that really drives me crazy is that it tips over easily, unless opened all the way, no matter how i arrange things inside. Since it has to be opened all the way, it takes up tons of space, so i normally have to set it on my floor, which is not convenient.
Honestly, i only keep it because it says mac on it, and for $225, that's pretty sad. I store my things it when i'm at home, but i travel with the carry all. I havent really seen the heat resistant aspect of it, and it definitely is durable though. If you really want a MAC case, i vote for the carry all. Holds tons, light, doesnt take up a lot space.
