DaYan brand ruled supreme within the speedcubing community for a number of years with the release of the ever popular Guhong and later Zhanchi (DaYan 5) edition speed cubes which dominated and were almost certainly the 'main' of many leading speedcubers around 2011 - 2015 including Felix Zemdegs who used the Zhanchi to break several formal world records . After a 6 year long hiatus DaYan again released two new magnetic cubes in 2019 - namely the GuHong V3 M and the TengYun M - both of these cubes selling well. The cubes are designed by Daqing Bao and manufactured in China and exported internationally. DaYan is the pinyin of his name "大烟头" (Da Yan Tou).
The logo on Dayan cube uses the last character "头".
QiYi 奇艺 (Pronounced Chi Yi) is a large innovative speed cube and twisty puzzle design and manufacturing company, which came to prominence in 2018 by making excellent quality cubes at budget prices. The company constantly evolves and expands their product range. They have had many successful product design collaborators, the most famous of which is Mats Valk who collaborated with QiYi to create the hugely popular VALK sub-brand.
QiYi operates a couple of popular sub-brands like:
The current flagship cube from QiYi is the X-Man Tornado V3
GAN Cube is an exclusive speed cube design and manufacturing company named after the designer and owner Ganyuan Jiang (江淦源).
The GAN Brand is famous for constant innovation and the GAN356 edition speed cubes are considered the premium 3x3 speedcubes available on the market today.
The GAN brand gained a huge following after our most famous speedcuber Feliks Zemdegs changed his "main" speedcube to the GAN357 model in 2015 and later became the brand's key ambassador. Multiple world records have since been broken with GAN Cube 3x3 Speed cubes.
