Received the cube today. The very first turns of the outer layers were fine but after turning the inner layers, the whole cube became very blocky. Now even when only turning the outer layers it gets stuck and i have to use some force or turn the other direction. Feels like there is something on the inside that gets stuck. In another review I read something about a core magnet came loose. Should I disassemble and have a look or return it?
Update:
The problem was that the core magnets came loose. I tried to glue them but didn't succeed. Support was nice enough to send out a new cube for free where eveything was fine!
