Xbox One Elite Controller Series 2 RB button Replacement

Less than 6 months of having this and the RB has to apply more pressure to work. To fix this I have to solder. I won't buy this controller ever again.

Me too. It's hard to believe, but it's true: the Elite 2 controller costs many times more than a regular one. However, its quality doesn't justify the price at all. In short: the price is much higher, and the quality is much lower. Shame on you, Microsoft..."

I keep having issues, I manage to remove the button but there is still solder stuck in the hole so I cannot passthrough a new button... I have used wick, solder pump and reflowing with new solder, nothing works?

Any ideas??
