Though the HP Omen Vector and Vector Essential Gaming Mice are different gadgets, they have some important similarities. First, these gaming gadgets weigh only 88 grams, which is just three ounces. That’s a seriously lightweight computer mouse. What’s more, the HP Omen Vector and Vector Essential each have six buttons. The Vector has higher specs, like the fact that it has an Omen Radar 3 sensor and sensitivity up to 16,000 DPI. It also comes with more LEDs and a side rubber grip with texture. This mouse can even come with 25 grams of extra weight. Moreover, with the five-gram weights on the bottom, it can end up weighing up to 113 grams. Alternatively, the mostly plastic Vector Essential has an Omen Radar 1 sensor with a maximum sensitivity of 7,200 DPI. Either way, you’ll get a gaming mouse that’ll respond to all your moves.
