track ir 5 or track ir 5 clip pro ?

[U505]

Since some time, i have been using the track ir 5. Actually, i find it quite helpfull still the image is stuttering at some moments, especially when i try to look downwards.So i wonder if it would be better with the track ir clip pro ?

Is the general quality of the game picture (more fluent) and comfort better -or far better- with the track ir clip pro ? Am pondering to get it if so.

Could you give me your point of view and your advices ? thanks
