REDUCE FOREARM STRAIN FOR MAXIMUM ERGONOMICS: Conventional flat keyboards force you type with your palms facing down. This harmful posture puts pressure on the forearm muscles and tissues which reduces blood circulation and can lead to fatigue and repetitive strain injuries (“RSI”) like carpal tunnel syndrome. Attach the V3 Pro accessory to your Freestyle Pro keyboard to elevate your thumbs for a significantly more comfortable and healthier typing position. THREE ADJUSTABLE HEIGHTS TO CHOOSE FROM: Ergonomics is all about finding the right configuration for your body type and workstation. The V3 Pro kit lets you choose from 5, 10, and 15 degree tenting heights for maximum comfort and easy reproducibility. EASY TO INSTALL: The V3 Pro kit attaches in seconds and doesn't require any special tools to install or adjust. Remove it any time
