the qi yi pentacle cube turns well and is pretty challenging if you try and solve the internal edges.

If you want more of a challenge get the sticker less and if you don't get black as there are no hidden edge pieces but in my opinion the sticker less is better

The Pentacle Cube came a bit sandy and loud out of the box, but after some breaking in and a bit of lube it becomes really good and fun to solve.

Its a challenge cube .. a mix of a 2x2 cube and bandage cube... you need to align the pentagram to move...in all its a good cube to practice 2x2 algorithms!!!

thanks

A really interesting solve on a puzzle that turns excellently!
