Yunzii B75 Pro vs YZ87: your questions
The Yunzii B75 Pro includes a multifunction knob. According to its product description, this knob can adjust volume and RGB lighting, and long-pressing it switches between gaming and office modes. The YZ87 does not have a knob.
No. The provided specifications list a 4000Hz polling rate for the B75 Pro. The polling rate for the YZ87 is not stated in its product information.
The YZ87 has a larger battery capacity at 5000mAh, compared to the B75 Pro's 4000mAh. This suggests the YZ87 may offer longer usage between charges, though actual battery life depends on usage patterns and RGB settings.
Yes. Both keyboards are listed with hot-swappable PCBs. The vendor descriptions for both state they support 3-pin and 5-pin mechanical switches, allowing you to easily change switches without soldering.
