Absolutely love this cube! well worth the money.
The official app is ok, and has some good features, but can be a pain to navigate. Connecting the cube to csTimer could really do with some better guidance/instructions posting online, however, once I got that working I was able to get so much insight into my solves (CFOP time splits and move count, solve reconstructions, and times without having to worry about hitting the space bar)
Not much breaking in was needed either, a couple of drops of lube and some time playing with tensions/elasticity/corner-core magnet strength and within a couple of hours this was a strong contender for a new main (It is my new main when I do timed sessions at the very least).
