The Turtle Beach Grip 500 laser gaming mouse is an ergonomically engineered, illuminated 7-button scroll wheel mouse that uses premium components such as Avago 9800 laser sensors and Omron switches to deliver steady, precise gaming control. It packs a number of powerful features, including the ability to customize performance, change illumination settings, program all seven buttons and the scroll wheel, plus create up to 50 complex macros with up to 100 commands each and then assign them to any button. They can then be saved into five different color-coded profiles, loaded into on-board memory and changed on the fly.
