I originally wanted to get the core collection but decided to get this instead because of the good reviews. The brushes are so soft and the feel of the handles is pretty decent. Definitely not cheap like those brushes that I get for a fraction of the price. I love the buffing brush and the contour brush. I can actually live with just the buffing brush if I ever have to pick just one from all of my face brushes! The flat foundation brush though, I don't use for foundation. I use it for contouring to make that line on the hollows of the cheeks. I use the detailer brush for concealing dark spots. I think RT brushes are expensive coz there are a lot cheaper alternatives in the market. But this set is worth it. You get 4 for the price and it's pretty good. I don't like the brush cup though, coz it's not sturdy to hold all of the brushes and it's too loose. Oh well, it's pretty much just a bonus.
