I bought this not knowing what it was really, I thought it was like a piramid style of puzzle, I was wrong! This is a shape changer and a cube, yes six sided cube, at several points during the first solve I had to walk away and rest my brain (I'm sure this will get less of an issue with future solves). The turns are smooth when everything is aligned but getting everything aligned can be tricky, also it has a good weight to it and you get a good sense of achievement when you solve it.
