The controller is shaped to be held in at least one hand of a user such that the at least one control is operable by the user. The at least one control extends through an aperture provided in the outer case, and wherein the controller comprises a removable buffer mounted within the aperture. ## Claims ### Claim 1 A hand held controller for a games console or other computing device comprising: an outer case comprising a case aperture; a thumb stick control disposed in the case aperture and coupled to the controller, wherein a lower portion of the thumb stick control is disposed internal to the outer case and an upper portion of the thumb stick control is disposed external to the outer case, and wherein the controller is shaped to be held in at least one hand of a user such that the thumb stick control is operable by the user; and a buffer removably coupled to the outer case within the case aperture, wherein the buffer comprises a buffer aperture and the upper portion of the thumb stick extends through the buffer aperture, and wherein the buffer is in sliding contact with the lower portion of the thumb stick control. ### Claim 2 (depends on 1) The controller of claim 1 wherein the buffer comprises an annular ring configured to prevent the lower portion of the thumb stick control, disposed internally of the outer case, passing through the case aperture. ### Claim 3 (depends on 1) The controller of claim 1 wherein the buffer aperture is arranged so as to prevent the lower portion of the thumb stick, disposed internally of the outer case, passing through the buffer aperture. ### Claim 4 (depends on 1) The controller of claim 1 wherein the buffer comprises a mechanical fastening means. ### Claim 5 (depends on 4) The controller of claim 4 wherein the fastening means comprises a bayonet style fastener having a male component and a female receptor. ### Claim 6 (depends on 4) The controller of claim 4 wherein the fastening means comprises a screw thread. ### Claim 7 (depends on 1) The controller of claim 1 wherein the buffer is configured to prevent the thumb stick control making contact with the outer case when in use. ### Claim 8 (depends on 1) The controller of claim 1 wherein the buffer is formed from a metallic material. ### Claim 9 (depends on 1) The controller of claim 1 wherein the buffer is formed from a plastics material. ### Claim 10 (depends on 1) The controller of claim 1 wherein the buffer is formed from a resiliently deformable material. ### Claim 11 (depends on 1) The controller of claim 1 wherein the buffer comprises a drive member for engaging with a tool. ### Claim 12 (depends on 11) The controller of claim 11 wherein the drive member comprises a one or more recesses defined in the buffer. ### Claim 13 (depends on 12) The controller of claim 12 wherein the tool comprises a one or more lugs for engaging with the one or more recesses. ### Claim 14 (depends on 1) The controller of claim 1 wherein the buffer comprises at least one end stop to limit rotation of the buffer with respect to the outer case. ### Claim 15 A hand held controller for a games console or other computing device comprising: an outer case; and a plurality of controls located on a front end and top of the controller, wherein the controller is shaped to be held in both hands of a user such that the user's thumbs are positioned to operate controls located on the top of the controller and the user's index fingers are positioned to operate controls located on the front of the controller, and wherein the plurality of controls comprises a thumb stick control that extends through a case aperture provided in the outer case and is moveable within the case aperture; and a removable buffer mounted within the case aperture, wherein the buffer is configured to accommodate an upper portion of the thumb stick control, disposed external to the outer case, and wherein the upper portion of the thumb stick control contacts the buffer when the thumb stick control is moved to a travel limit within the case aperture. ### Claim 16 (depends on 15) The controller of claim 15 wherein the buffer is arranged so as to prevent a lower portion of the thumb stick control, disposed internally of the outer case, passing though the case aperture. ### Claim 17 (depends on 15) The controller of claim 15 wherein the buffer is configured to prevent the thumb stick control making contact with the outer case when in use. ### Claim 18 (depends on 15) The controller of claim 15 wherein the buffer comprises a mechanical fastening means. ### Claim 19 (depends on 15) The controller of claim 15 wherein the buffer is formed from a plastic material. ### Claim 20 A retainer for securing a thumb stick control to a hand held controller, the retainer comprising: an annular ring couplable to the controller and comprising: an aperture for receiving an upper portion of the thumb stick control; and a first part of a securing mechanism for engaging with a second part of the securing mechanism provided on the controller, wherein, with the annular ring coupled to the controller, the annular ring is in sliding contact with a lower portion of the thumb stick control, and wherein in use the upper portion of the thumb stick control contacts the annular ring to limit travel of the thumb stick control and to prevent contact between the thumb stick control and an outer case of the controller.
