Negative Positive
Title: Good idea poorly executed.
Review: I have tried most presentation pointing devices on the market. The Phaser is better than some because it has a trackball instead of a minature joystick or hatswitch. But the Phaser appears to be built very cheaply. It uses mechanical rollers instead of optical technology, and the rollers, which are attached to flimsy little bent wires, easily lose contact with the ball. Perhaps I got a lemon. I returned mine and bought a Gyration Ultra.
Is the review positive or negative?
