How hard are these puzzles?

[Eleredo]

I'm buying a SQ1, 2 and a Master Pyramorphix.
They look quite intimidating. Just how hard to solve are they?

Squares are hard to do intuitively. The other one is just shape shifting to make up for it's inability to be misoriented. Probably not as hard.

At first, they are quite hard. But once you got it all down packed then your good to go.

i cant figure out square 1 and super square 1 but master pyramorphix just takes getting used to the shape shifting and remembering which piece is which on a regular 3x3
