It is ok, but you do not get the yeah this machine feels "solidly awesome" like I got with older Thinkpads 420, 440P or older Dell's Precision lineup.
The real show stopper was that Lenovo used some no name Chinese made M2 SSD as the primary, leaving more respectable WD in a secondary slot.
The no name SSD failed without warning in a year.
So check your SSD makers.
