Razer raiju tournament edition ver 1.5

So i had an issue few months ago about this controller, then i returned it to the shop for the warranty claim. They replaced the controller, I've been read some thread that they had out of the box ver 1.4. Surprisingly when o check the newly replaced controller. I've got the ver 1.5 with no issues, no dead zone and stick drift or ghost movement after few hours of playing call of duty black ops 4.
