Includes the Razer HyperPolling Wireless Dongle. It minimizes latency with 4K and 8K polling rates. The mouse feet have been replaced with Super Glide v2. I used it for about a month, but it didn't fit my hand, so I'm selling it. Please feel free to ask any questions in the comments. Please understand that this is a used item before purchasing.
