I've only tried the mini Chacha tint that came as a gratis gift so far. The color is truly perfect for warm skin tones and seems suitable for both spring and fall. I have a deep undertone, and I think the color is absolutely gorgeous.
The quality doesn't seem that great. It has the yogurt effect (separates). The staying power is poor. The color payoff isn't very strong, so you need to apply multiple layers.
It seems this works best as a base lip color since the pigmentation isn't very intense.
