Logitech developed it together with PixArt, I'd bet this one will stay exclusive to Logitech forever, just like some Avago sensors never came to other brands than Logitech (e.g. A3080E, S3095) respectively Razer (S3668, S3888, etc.)
So far I only tried the Puretrak Talent and the Zowie GT-F Speed. Worked perfectly fine on both. After tuning to the Talent I had to retune for the GT-F Speed though, because with the Talent setting it would skip sometimes on the GT-F Speed.
