Wheel Scroll - fantastic easily the best of any mouse.Buttons - relatively light but feels good to use.Due to these reasons I returned the mouse. I still have my MX518 and directly compared them and the G502 doesn't feel anywhere near as nice in the hand. Shape - I wanted to love this mouse, as I loved my MX510's but it just felt too narrow and uncomfortable.Sensor - Performed well, no issues noticed, but didn't 'feel' the best to me (weight and shape could have contributed to that though).Wheel Click - feels good, stiffer than DA but lighter than EC1-eVo.Shape - It's a relatively small mouse, slightly odd shape but can be comfortable.Sensor - feels great easily as good as the EC1-eVo.Wheel Click - good weight, stiffer/heavier than the DA.Wheel Scroll - heavy with defined notches.Buttons - heavier than the DeathAdder, side buttons are mushy.Shape - Mouse is a nice shape (possibly nicer than the DA), but it's larger than the DeathAdder and simply too big to be comforatable for me to use (I should have bought an EC2, and I still might).Sensor - feels great, maybe not quite as 'snappy' as the chroma but it feels great.Wheel Scroll - feels good, defined notches.Shape - good shape, (feels slightly too big for my hand size though),.My brief observations of my current mice are: I have or have had, mx510's, mx518, all the DeathAdder versions (because they all developed double click issues except my chroma it's only a few months old), Zowie EC1-eVo, Mionix Caster, Finalmouse 2016, G502 and Steelseries Rival 300. So at this point I think I have a bit of a mouse addiction.
