It feels like a little racecar, nice lines and well built, but the mousewheeel is a bit too far back. The shape imo is very good, g100s level (to me god tier). It feels very small, the hump is tight and high, the buttons are wide and feel good (comfort grooves) and the base has an inward curve from the rear the front, kinda like the avior, takes some getting used to. Ive changed the cabl on mine because the stock cable was wayy too stiff also got it down to 62g.
They didnt answer you probably becausee you need to be some kind of tech journalist or have a youtube channel to get free samples?
Currently I believe the palm grill provides a bit of breathability but at the cost of gripping surface, not sure if i like it or not but its not too important.
