Ghost cube give an interesting challenge in solving the cube, unlike mirror cube where you can easily align the cube and find out which pieces goes where, ghost cube are not as simple as that, especially the center pieces can be rotated and make correct pieces looks incorrect at times.
For whom looking for a challenging cube to solve intuitively, compare to other well known challenging cube like gear cube extreme and Latch Cube, this one is much easier since it is ultimately, just shape mod and you dont need to create any new alg for this cube which make it much easier.
However, the cube's sticker quality disappoint me. Out of the box, most of the stickers are stick fairly poorly, and either seems like it will come off anytime or and interfere with your turning. Some of those stickers, if you told me a 1 year old child stick those stickers on, I might have believed it. Moreover, some sticker's color seems to be slightly off. However, ghost cube can be a sticker-less cube, so I just removed the sticker and go with it. No big deal for me, but might be a deal breaker for some.
(Note: The photo I attached might be hard to see, but it shows some peeling and sticker color comes off. I have removed the worst stickers at the time of this review since it is completely unbearable during my initial solve)
