XtremeComputing has posted a Salient VM223 wireless Pen mouse presenter review
Salient advise the best way to hold the Pen is with your index finger resting over the lower button in a relaxed grip but to keep your wrist and arm in a fixed position which will then allow you to enjoy the natural, precise, smooth writing style operation that the mouse gives you. When the device is switched on there is an optical light source that glows blue out of the end of the pen and with a working distance of up to ten meters the device should work well.Salient VM223 wireless Pen mouse Presenter Review
