QJ Pyraminx
From Speedsolving.com Wiki
The QJ Pyraminx is a Pyraminx puzzle produced by QJ. It is available with tiled or smooth stickers. The tiled stickers are known to fall off but are grippy unlike the stickers. The turning has a unique ball-bearing design to prevent over turning which other Pyraminxes can tend to do. It has a clicky ball-bearing feel with the inner layers; the tips turn very smoothly. It corner cuts to around about 1/8 of a piece. At the time of its release (c.2010), it was one of the most favoured and best Pyraminxes.
