ROG Ally X triggers

so i got a replacement ally x i got the og ally but returned it because it had a stiff bummer that was fine until pressing it a couple of times would get it to stiffen and then i got the ally x and it would freeze everytime even after several restarts) now with this one is working great the only thing is that the triggers are weird in the sense that the left one is quick and more lighter to press but makes a clicky noise at the end and the right ones is great sounding just that after awhile of pressing it it gets slightly harder to press. i showed it to my mom and she didn't notice it at first but then after pressing it a couple times she realized that it got slightly harder to press them the first time and she just said it was because it was new and had to be broken in kind of thing but i don't think so
