Razer Naga Trinity Left Click sometimes not Working

Title says it all, here's some extra info.

-My warranty recently expired
-Sometimes harder presses get it to work, albeit very temporarily (pointing to physical malfunction)
-An identical mouse works on my computer without issues (so definitely hardware not software issues)
-I don't abuse the mouse at all.

After figuring this out, I figured I would just open the damn thing, only to find out they made it as hard as they can to service on it. I've fixed many keyboards and mice before but there is no physical screws I can access to get it open.
Older versions of the mouse, from videos I've seen, have screws under the desk sliders, but there is some solid plastic under those now.
What are my options? Because it's definitely not going to be buying another one, if they just stop working like this.
