Pulsar X2H Review
The main difference between the Pulsar X2V2 and X2H is shape. Whereas the hump on the X2V2 sits rather low, the X2H has a high hump. The X2H still comes with PixArt's PAW3395 sensor as well as optical main button switches, and the weight too is similar at 52 g and 54 g for the two sizes.
