Razer Deathadder Elite keeps double-clicking, and losing click-hold

I have a Razer Deathadder Elite, that I bought from Target less than two years ago. It just started double clicking and also when I click-and-hold... it "lets go" on its own and sometimes clicks and holds again. It seems the Omron switch has gone bad. This is the *2nd* Razer mouse I've had this same issue with. The first mouse was used, so I kind of figured it might have been just old age. But this mouse, I've had only about a year and a half so far. I'm very disappointed. Especially since when I looked up the SN, it is telling me it is out of Warranty... but supposedly, Razer's Mice products have a two year warranty. I bought this at Target on 4/1/2019
