Mamba & Firefly Hyperflux

Hello,

I come to ask for your help regarding a device. The Razer induction mouse pad and its mouse: The Razer "Mamba Hyperflux" and the "Firefly" pad (1st version).

For some time my mouse has failed (the pointer has no problem but when I keep pressing Left Click, it very often loses its lock. So I lose my selection and have to start over several times to in a row before finally succeeding in moving a document or making a selection).

It's not really a problem because I told myself that I would just have to buy a mouse (Mamba Hyperflux).
Little did I know that after a long search on the internet, I would never find the possibility of buying only the mouse. This is only the complete bundle (mouse + mat).

So I tried to find information everywhere, but no site or forum has ever mentioned it, I can't find anything.
To believe that I am the first who asks the question.

So the last possibility I have left, I ask the question here.
I still imagine not to have been the only one to have bought this peripheral and nor the only one to have the mouse which begins to tire.

Do you know if it is really impossible to get the mouse alone?
And if so: If other Razer wireless mice are compatible / work with the mat (even if I wonder about detection in this case)?

Thank you in advance for your interventions.
