Agreed! When I wasn't sure if I needed a primer, and didn't want to invest a lot to find out, I tried this. I used it for a while but then set it aside. I didn't notice a big difference in how my makeup looked or lasted for the day.
I've gotten samples of various primers and recommend getting some from Sephora or department stores if you are considering high-end.
