At around $15 USD, these seem pricey, at first... especially since you can find controllers starting at around that price (well, not the sturdiest of controllers, but they're out there). These aren't controllers on their own, but can enhance multiple controllers you already have - across different systems. In fact, if you only want to enhance one side, you can use a single pair of KontrolFreeks on two different controllers. You could use your ELITE
s on the left analog stick of your favorite PS3 controller and your favorite Xbox 360 controller, for example.
The only two possible problems I can think of with any of the FPS Freeks are issues with them fitting some controllers (although they fit a good many) and storing them safely, if you tend to take them off of the controller when not in use. Mind you, there's not necessarily a need to remove them from the controller when not playing, but if there are small children or animals who may attempt to eat them, for example, you'd want to put them up for safe keeping. Sadly, no storage case is provided and these things are about the size of a bottlecap, so fairly easy to loose.
If you're looking for some increased accuracy and a little added height to your analog sticks, the FPS Freek ELITE provides that along with a sweet solid black color scheme, which gives it a slicker appearance, in my opinion.
