I originally bought this palette because of the amazing reviews. I've not had a problem with any of the shimmer colours - they are absolutely STUNNING and redeem the entire palette but the mattes are so disappointing. I've used the palette for a month to test it out.
The colour payoff when swatching the mattes is fantastic but when you actually come to put it on your eyes it doesn't work as they come out much more sheer or too similar to each other - Zakiya, Nana and Kogi both come out as an indistinguishable orange toned brown and take some serious work to build to a colour recognisable to the colour in the pan. Ife and Yejide come out as too similar dark, difficult to blend navy/purple colours. I have no problems with Kesi however it is very close to my skin tone. I've tried combinations of brushes, primers and I've even given the palette to other makeup enthusiast friends to try out - all to no avail as they have had the same problem.
When you try to blend the mattes, I've been unable to get a nice clean blend without it being patchy or merging into an awful colour despite them being gorgeous when in the pan or swatched. The matte eyeshadows themselves are chalky in the pan. We've been unable to get the matte colours to stay on longer than 4 hours without noticing a significant fade regardless of primers, brushes, setting spray or application method. I've not had this problem with other similar palettes which suggests it's not a technique problem.
The shimmer colours, however, are absolutely gorgeous - particularly Vai, Yemoja, Nubia, Osun, Yara and Faso. The pigmentation is strong when swatched and when applied to the eye with either a finger or a brush. I've received many compliments whenever I've worn a shimmer and I've had none of the problems that I have had with the mattes.
I guess you do only receive 6 matte colours out of 16 colours included in the palette but I can't give this palette recommendation as a go to palette due to the matte colours. If it had been a 10 pan 100% shimmer colour palette, then this would have received full marks and a very high recommendation. If you're looking for shimmers, I definitely recommend this palette if you're looking for some 'out there' shimmer colours or as a staple palette for anyone that enjoys experimenting or vibrant looks. I wouldn't go for this if you wanted a high pigmentation matte though.
