Overview:
More and more people are discovering the benefits of using an ergonomic mouse. The J-Tech Digital V638 wireless ergonomic mouse is designed to allow for more natural movement, eliminating wrist/hand/arm strain. A detachable non-skid palm rest makes it easy to move the mouse around any non-metallic surface. Wireless connection means users aren’t tethered to their computer by a cable (2.4GHz Wi-Fi connection only). Add in the 360-degree signal, convenient thumb buttons, optical tracking technology, adjustable DPI, rechargeable battery and its compatibility with a wide range of computer operating systems and it’s easy to see why so many people are making the switch to the JTD V638 vertical ergonomic mouse. We understand that the V638’s innovative ergonomic mouse design may be a little intimidating for some users. We urge customers to use their wireless ergonomic mouse over a period of days to get used to its unique feel. We know that once you’ve become familiar with its comfortable, easy to use design, you’ll be asking yourself why you didn’t go ergonomic a long time ago.
