I bought this along with a 6x6 X-Man Shadow M. These were my first non-Moyu cubes. Like the 6x6 Shadow M, I purchased this based on reviews on a number of sites.
Since I got the 6x6 Shadow M at the same time, this one has been on the shelf for a few days. I opened it tonight and did my first solve in order to write this review.
OOTB, I really like this cube! It turns really well and I'm able to flip all 5 middle layers with a single finger without much difficulty. I can definitely feel the magnets in this one, which makes me wonder if I got a bad 6x6 Shadow M since those magnets feel really weak. There is a fair amount of lube on the outside of this cube though I'm sure it'll wear away after a few solves like the 6x6 Shadow M.
I would definitely buy this again.
