for his 4.74sec solve in November 2016. Lucas Etter used an Aolong V2
for his 4.90sec solve in November 2015. Feliks Zemdegs the most famous solver ever used a Gans 356S
for his official 5.84 sec also in November 2015. Mats Valk used QiYi Thunderclaps
when he broke the world record for most solves in one hour in December 2015. Collin Burns used a YuXin
