Razer deathadder Essential review

I've owned a fake razer viper mini and it sucked. The sensor was blinding red and the side buttons didn't work. Now I wanted to get a real one without breaking the bank and I got the deathadder Essential. What I can say about it is that it's absolutely incredible, super high quality, beautiful led light and even mechanical clicks! It also has an infrared sensor (I think) and the sensor light is invisible to the naked eye. The tracking is good too! I have worried a bit about the weight but guess what? It improved my aim! My aim isn't shaky and it's light enough to move it around fast. In my opinion it's the budget king! What do you think?
