Raiju ultimate again. On my third replacement

I'm getting more and more frustrated with this controller. Bought it last year in september. We all know that the first generation of the raiju ultimate had problems such as input lag and stick drift. As of now i'm on my third replacement. The new batch of raiju ultimate controllers had new firmware installed (1.04). My second unit was of the new batch. No more stick drift or input lag. However it had major Bluetooth issues. Now my third replacement with firmware 1.04 seemed flawless. Yes it seemed. Though i dont have any issues such as stick drift, input lag, or even Bluetooth problems. My L2 button is sometimes stuck. Wether it's in hair trigger mode or not. When i blow inside the controller it goes away. Today i bought a compressed air can spray. It worked.......for 10 minutes. Right now i'm at a point that i'm starting to think that this controller is cursed by all the gods that excist. I contacted razer support, they want video proof. Again. I really love the design of the controller, the way it looks and feels. But man, if it would work without these problems. This controller is 3 weeks old. I always take really good care of products like these. Being a working dad, my gaming time is precious. So please Razer, step up your game.
