Yes, the hyperpolling dongle is included in this version of the Deathadder V3 Pro.
Please note that the hyperpolling dongle that is included cannot be unpaired from the DeathAdder V3 Pro that it comes with, nor can it be paired to any other mouse. In fact, the Hyperpolling dongle is the only included dongle (no regular 1k dongle), and when you connect it to your PC, Synapse sees it as "DeathAdder V3 Pro", not as HyperPolling dongle as with the regular version. Still, it lets you set up to 8k polling and for all intents and purposes it works as the regular Hyperpolling dongle, you just won't be able to unpair it from the Deathadder V3 Pro.

Additionally, the coating on the mouse is different: it's smoother but also a bit grippier than the original coating.

It's currently my favorite mouse, while waiting for the Viper V3 Pro to finally be released. :)
