Of the four products I have bought from MR, all of them have had good quality. I have one lip product I particularly like; it is a lipstick of a rose pink shade. The texture is very smooth and moisturizing and although it is not matte it is not sticky either.
I have one setting powder from AB but I don't use it too often. I use another brands instead. However, if you are looking for a good priced powder this is a good one! It hasn't given me any problems, and it does it's job.
