TBH this cube pushed me to sub 15, but I just couldn't seem to adapt to the noisy sounds, like I forget my memorization during 3 bld solves. the only loose settings usable are I think compression 2 and tensions 4( which allows it to not pop.
if you really want to get a gan, spend a few more bucks and get the maglev at max.
a biased opinion is that I hate gan,, like it is so less for what you pay. honestly get the moyu cubes or the tornado ( v3 or v4). my main is the ys3m bc my average is 13 secs, innacurate but soft turning. gan 12 corner cutting is ok. but please don't buy the gan 12 leap.
the magnets keep switching from high to low. if you really want an adjustable magnet cube, get the wrm 2021 maglev or lite.
