This mouse is flawed. It does not satisfy minimum voltage requirement for the switches it uses.
I took these screenshots from Omron D2F (Japan) datasheet (
https://omronfs.omron.com/en_US/ecb/products/pdf/en-d2f.pdf):
Omron switches require at least
5VDC. But I have just measured with my unit and it provides only
3.3VDC.
I'm experiencing double click issues already with both left and right side (happens when pressed at an extreme offset). This is probably a generic issue and not related to the specific one I have.
The China switch is said to be not micro-load model. So I believe it is even worse when Japan switch is not used.
This problem is explained in detail in this video: It probably has to do with the MCU used in the mouse that operates at 3.3V.
On the other hand, the software that comes with it is pure crap. It shows battery levels with 25% intervals. It takes forever to load and it installs services and consumes a lot of memory. It is just bloatware. I was using Logitech G Hub and I hated it but when I compare, G Hub is the best software ever written.
Therefore, I do not recommend buying to this mouse.
I think
@pzogel should mention about this voltage issue on his review so no one buys this crappy designed mouse.
