ลูกบาศก์ปริซึมเฮกซาสตาร์

The puzzle is enourmous, but feels comfortable in your hands. Turning is great if you are capable of aligning the rails correctly. Stickers are good quality ones, so I think you wont have any problem with them. Algorithms feel a bit weird, because the cut is really deep and the mechanism is jumbling-only, so making cycles can be hard. This puzzle is a real challenge, and I'd like to see more information about people trying to solve it, so we can all learn new algorithms for it.

This is a rails mech puzzle unfortunately. Mine split in two on its first turn and I haven't put it back together yet. It remains unstickered. It is also insanely huge, far too big and awkward to scramble and solve comfortably even if it worked well, which it doesn't.
There are lots of other puzzles out there I would recommend before this unless you absolutely have to have every puzzle.
