I have been using the products of this brand all my conscious life, "not without sin", for example, in Diamondback 16000 dpi, the sensor was bugged . (periodically, once a month, two, it started to freeze for 30 minutes, then it went away (let go)). Cost, today (purchased with delivery for 4400r), in the USA it costs $ 80 (still, but this is not accurate), branded stickers are included (very beautiful), but it would be better if there were 2 snakes than 1 snake and several small ones with inscriptions. Very light, the appearance is 4 (maybe a homogeneous mat), there is not enough polished plastic, like on a death-sadder, for example, in combination with it, the mouse looks richer. Very light, excellent sensor, tenacious and accurate.
