What I took into account in the shortcomings is not exactly a shortcoming, since the mouse is significantly cheaper than other new mice in the DeathAdder series, and therefore these shortcomings are simply forced measures to make the mouse cheaper. I have been using the mouse for almost a month, and during this time I have not caused any complaints. I bought it for 3800r in Hong Kong time. There is a backlight, but only one color - green, soft-touch plastic coating of good quality. The sensor does not break and behaves well on both black and colored mats. If you want the DeathAdder but don't want to pay a lot but still get the same functionality, then I can safely recommend this mouse.
