To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
However i find that for some reason they pop off too regularly which is quite annoying.
Previously i had used quite large concave style thumbsticks for a few years. But i found i was bending the top of my left thumb too hard. So look for a change. Was recommended these. Which are so much better.
Only grievance is the looseness of the the fitting.
These things really do improve accuracy, more so on FPS (first person shooter) games. I have used for years and these are the best yet. Give them time to wear in as the design was hurting my thumbs at first but after a week or so of using the rubber wore down and became soft. Used for many months now and no issues....
