Roller bearing idler arm question?

Does anyone have experience with a roller bearing idler arm?

I understand this mod will make my manual steering easier to turn at very low speeds.
I also read that the roller bearing idler arm is for track only as it will not allow the steering wheel to return to center properly.

I’m trying to make this car easier for my wife to drive.
Can anyone with experience please square me away on the pros and cons of this mod?

Thanks
