The cube is fine - nice and smooth, nothing wrong with that.
Still, the only thing it can do in the "smart" mode is scramble; as soon as you get it out of the robot, the app just loses the cube, and the timer shows a completely solved cube, rendering all the extra money you paid for the "smart" features almost completely useless.
Excellent customer service. when I emailed, i got a response back quite QUICKLY. The guy was quite helpful, and answered any questions I had.
Unfortunately, due to the low quality part, the spare piece I had ordered broke after a month or so. However, this isn't the fault of speedcubing.org in the slightest. Simply a cheaply made part.
I would highly recommend this site.
