As shown in the video above, you can pair two 8K compatible mice on any Pulsar 8K dongles. This is great if you have two Pulsar mice that are 8K compatible, and you like switching from one to another without the need for two different 8K dongles. This is also great if you only want one 8K dongle on your desk, and want to switch mice quickly.
Please note that both mice need to be compatible with the same dongle. Even if both mice support 8k or 4k polling rate, that doesn't automatically mean that they use the same dongle, as not all 8k or 4k dongles are the same. Therefore, we'd suggest being careful with this.
