The HP Omen Reactor mouse is a mixed bag, but worth hanging onto if you can get it as a pack-in for a new PC, or at a discount.

Novel design; Good performance; Sensible button layout

Adjustable palm rest doesn't work well; Not that comfortable; Pricier than competitors

I bought the mouse for my son's and they love it for their gaming experience

The mouse has incredible responsiveness and glides smoothly, my only concern is that this mouse is heavy, and although precision players may not notice this, a speed player like me definitely did. It has a wide selection of buttons however which made me appreciate its value even more.

The ergonomic design really just seems to work for right-handed people, which makes it comfortable for me but not my sister. The back of the mouse comes up pretty far, and is adjustable way up or down, for ultimate comfort.

Excellent mouse, I would definitely recommend.

Looks great, very responsive and thoroughly happy with my purchase

This is a very responsive mouse with high accuracy and very comfortable using it continuously for several hours even without a palmrest, as the back end of it is adjustable so it can keep your palm at an optimum angle. Overall quality of materials is also very good as far I can tell.

The HP Omen Reactor is an unusual beast. One that at first glance presents a gaming experience that's relatively familiar, yet under the hood you'll find a few features that we've seldom seen in the enthusiast mouse space before.

Sharp; attractive design; Plenty of oppurtunity to customise; Feels fast and responsive where it matters

RGB lighting doesn't stand out much; Cable noise can be a bit distracting

Credit where it's due, it really does feel like HP did their homework with the new OMEN Reactor gaming mouse.

Metal-braided cable; Adjustable design

Plastic feel; Uncomfortable thumb-rest

Even with a few compromises, the HP Omen Reactor remains an excellent gaming mouse at this price.
