Although small it is very solid, which for firmer footprints does not present fragility when squeezing the mouse, besides being very light and pleasant to the touch.
Weight that makes it an extension of the body itself, with extremely responsive tracking sensor and clicks and with flexibility of configuration via driver.
For use of high refresh rate (4000/8000Hz) the battery drains very fast, which I understand as weak point due to the short duration for this specific use.
I used brands like Razer and Logitech, but ATK makes peripherals of the same level, or rather, costing much less is currently my favorite brand for peripherals.
