razer raiju ultimate problem

hi I bought razer raiju finished about a year ago, but almost immediately I sent it back for the known problems with the levers, which moved by themselves. I waited a month and a half for the new controller from china pm1903 updated to firmware 1, 5.this controller went pretty well only occasionally while I was running in my fps (shooter), the character stopped running and I was forced to press the lever again ... but today it's much worse, in fact while I'm running the character stops completely like if the command no longer comes..somebody knows how to help me? I'm desperate even after a year the controller is to be thrown away?
