KontrolFreek is a company that makes video game accessories that snap directly onto the control sticks for Xbox and PlayStation handheld gaming controllers. These add-ons are compatible with both the new PS4 and Xbox One controllers as well as older console controllers like the Xbox 360 and PS3. They are designed to improve gaming performance, accuracy and comfort. KontrolFreek offer a large variety of different styles and colors like the FPS Freek Vortex which is designed for FPS (first person shooter) games like the new Destiny game where accuracy is of upmost importance. Each package comes with two extenders, one convex stick and one concave stick. The taller FPS Freek is about a half inch tall with a convex top and is intended for your right thumbstick. It gives you more leverage and precision while aiming. The lower profile Freek has a concave top, is only 0.30 inches tall and is designed to add grip to your left thumbstick without adding too much height. Both Freeks are soft with a comfortable rubber thumb pad that has ridges that help keep your thumb right where it needs to be. The FPS Freek Vortex is available from KontrolFreek for $13.99.
