RVU Left Click Issues

I bought my RVU about 4 months ago and I feel like I am running to issues with the left click not working sometimes.  I know that if I blow into it, it starts to work, but that is only a temporary fix. Any ideas?

And here I thought the RVU would would be my salvation after a string of double clicking Logitech G703's.

It could just be in my head, but I feel like there is an issue, but mine could just have a lemon or something.

Nvm it was the human benchmark aim trainer not the mouse.
