As a person who coveted price over performance for many years, I have owned a plethora or mice in the budget discount market. Feeling that if I spent a third of the price of name brand mice, and still got 2-3 years of use, then I was winning the game so to speak. After my last mouse started not registering clicks at the most inopportune times, I finally realized that I needed to look at a quality mouse. That's where the Razer Deathadder Essential comes in. What a world of difference!
The Good: Size. It is LARGE. For someone with larger hands, typical mice in the budget category were often just adequate to just a bit too small. The Deathadder fits and feels like a substantial extension of my hand. Weight. The Deathadder is heavy. Not ridiculous heavy, but heavy enough you feel you are moving something. I happen to love this about the Deathadder. It gives me the weighted feedback that I am moving the mouse in a way that I want, not by accident because it was too light and it lifted and shifted it's position because of a minute twitch of my wrist. Adjustable: Having multiple dpi and mhz settings allows me to fine tune the Deathadder to suit my use case needs. 5 settings will be all you need to choose what works best for you.
The Bad: Lighting. The single color lighting would be nice if I could adjust that single color to fit the theme of my setup instead of just the Razer Green. If there is a way to change that color in the software, it's well hidden. This is a cosmetic thing and in no way adversely affects the performance of the Deathadder.
Overall, if you are a person with larger hands, that wants a mouse of substance to help you perform better in game or on task, and comes in at an EXTREMELY budget friendly price, this is the mouse for you!
