Full-Size Ergonomic Comfort: The ProtoArc Ergonomic Keyboard features a unique curved split-frame design that actively reduces strain on your wrists and forearms and promotes proper posture. The scooped keys are crafted to fit your fingertips perfectly, making typing effortless and natural. Please note: we recommend checking the dimensions before ordering to ensure an ideal fit for your workspace. (While our full-size ergonomic keyboard enhances productivity, it may occupy more desk space) Learning curve: Since it takes some time to adapt to the keyboard layout when you first use our ergonomic keyboard, it may cause inconvenience to your use, We recommend that you take 1-2 weeks to get used to it, but our ergonomic design will help relieve the muscle pressure on your wrists and forearms Adjustable Backlighting: The ergonomic keyboard features soft white LED backlighting with three adjustable brightness levels (Low, Mid, High), allowing you to customize your comfort in any lighting. You can also turn the backlight off entirely to conserve power. This flexibility directly impacts battery life: enjoy up to 12-13 hours in High mode, 18-20 in Medium, 34-36 in Low, and an extended 90-100 days with the backlight off Cushioned Wrist Rest & Adjustable Tilt Feet: Experience comfort with our ergonomic keyboard.
