This is pretty much my first 5x5, but I am really big fan of it.
The black internals makes this 5x5 look unique compared to other 5x5 I've seen, it is quite fast and has pretty strong magnets. However its hard to turn the middle layers due to the strength of the magnet.
However corner cutting isn't that great (If you don't have a chaotic turning style, you will probably like this puzzle)
I only got this because how unique it is, and I can simply say I really like the performance of it and the overall quality of it!
(Also the turning sound of this 5x5 sounds quite pleasant to hear)
