A few months ago I bought a KontrolFreek CQC for my PS3 controllers. After about a month, they began to loosen severely and eventually became unusable. While I liked the CQC's extra height, they were poorly made and never stood up on a real controller. I was pretty sure I would never buy a KontrolFreek product again. A few weeks ago my boyfriend introduced them to me and I tried them out in his dorm. He's been using them since BO2 came out and they still haven't fallen apart. I decided to give them another chance and I was right. They add about half an inch to the height of your thumbsticks and greatly improve your accuracy. They're great for people playing at higher sensitivities so they can aim at over-aimed targets as quickly as possible. The best part is that they are damn strong. They never fall off my controller and are great to use. If they fall apart in the next few months I'll change my rating, but for now this is a great pair of thumb tweaks for almost any FPS.
