Review on Black PERIMICE-720 Wireless Ergonomic Trackball Mouse With Adjustable Angle By Perixx - Boost Your Productivity by David Ocampo

This is slightly big and took some getting used to. I normally use logitech trackballs but we must used wired equipment at the office and logitech wired products are too expensive.The ball rolls smoothly and once I got used to the form and grip of the trackball housing, I can mouse a lot quicker. It was plug and play and was easy to set up. I love that this came with two different bases to adjust the height and tilt of the track ball. It's magnetized so its easy to pop on or off.My wrist no longer aches from using my computer all day.
