I painted my bedroom a few months ago and used the Behr primer and paint in one and it was horrible! I didn't ask for it but that is what they mixed for me so I just went home with it figuring it would be great. I was so wrong, the coverage was awful and I went through almost an entire half gallon for my room (which is not normal), and I had to buy another one because it needed a second coat. I have used Behr paint before without any issues but I will never use their primer and paint in one again!
