Razer Mamba Hyperflux Mouse Replacement

I have the razer mamba hyperflux and it's been solid up until about 6 months ago. I've noticed slowly over time that my click and drag is no longer working very well. It will occasionally behave as if I lifted off the click portion, so imagine trying to highlight text, and as your highlighting it looks like you've let go and started to highlight further on. I've come to terms with perhaps its the cheap plastics that are losing its contacts within the mouse. Are there alternatives to buying a replacement or am I out the full combo because I can't buy another mamba hyperflux mouse? Will the regular mamba wireless mouse still charge and work on my hyperflux pad?
