Q16: Why is there a lagging issue sometimes when using the wireless mouse or keyboard?

The reason for the lagging issue might be as follows:

The broadband noise from the USB 3.0 data spectrum is in the 2.4-2.5GHz range. If the antenna of a wireless device operating in this band such as 2.4GHz is placed close to any of the USB 3.0 radiation channels, it will pick up the broadband noise. Thus it will affect the SNR (signal-to-noise ratio) and limit the sensitivity of any wireless receiver.
All electronic products will have some radiation. The radiation is diverging in the form of electromagnetic waves. When the electromagnetic frequency of this radiation is just about the same as the operating frequency range of wireless devices--2.4Ghz, it will interfere with wireless devices.

Q17: Why does the hub get warm during the usage?

Generally, the hub will get warm during usage due to the following reasons:

Once connected to a USB-C laptop, even though you didn't insert HDMI/SD card, every function module of this product starts to work and generates heat from its working current.
Compared to the plastic case, the aluminum case is better for heat dissipation. The heat of Electronic components and circuitry will be conducted outside more quickly, making the USB C hub safer for us.

If it gets very hot, and the hub cannot work properly, please stop using it and let us know.
