I came accross this product accidently on Saturday, and I am very glad I did!
When I put it on it felt smooth and creamy, and was increadlibly lightweight. Surprisingly it had a sheer finish, as apposed to the usual matt look, so no gloss was needed. It also smells quite pleasant.
As far as the 14 hour part goes, not quite. I ended up re-applying it 3 times during an average working day (mostly after coffee/meals), which was not too bad, but definitely not 14 hours! But the lipstick never went flakey, which I'm greatlful for.
