Although most mice require software for customization, this particular mouse stands out because it doesn't require any additional software. This is a great selling point since it allows users to easily adjust settings without the need for installation. However, the downside is that if you don't use the advanced features frequently, it can be difficult to remember how to utilize them. Additionally, I want to commend Zowie for offering different size options for each mouse model, unlike other manufacturers that offer a one-size-fits-all approach. In terms of battery life, it is not as long-lasting as the G502 Lightspeed, but still respectable. If you prefer a minimalist-looking mouse that offers similar capabilities as Razer's, the Zowie EC2 is worth considering. However, if you prefer a more luxurious feel and LED lights, the DeathAdder V2 might be a better option. Personally, I don't mind relying on Razer's software to adjust settings like polling rate and liftoff distance. CPI stands for counts per inch, which refers to the number of times the mouse sensor reads its tracking surface, typically a mousepad, for each inch moved. It is often referred to as DPI, but CPI is the more accurate term. Lower CPI means you have to move the mouse further to move the cursor on screen. The G502 Lightspeed, with its Logitech 16K Hero sensor and reduced weight, is compatible with the PowerPlay charging mat, offering a forward-looking wireless experience. The MX Vertical, on the other hand, is a luxurious mouse that provides a comfortable grip. IPS, or inches per second, measures the maximum tracking speed of a mouse sensor. The higher the IPS, the better it can keep up with fast movement, ensuring accuracy. Jitter refers to inaccuracies in the mouse sensor's tracking of the surface. It can cause the cursor to jump unpredictably or result in misclicks. Razer's HyperSpeed Wireless offers fast wireless technology trusted by top esports athletes, with extended Razer Chroma lighting zones and up to 50 hours of wireless gameplay. The Basilisk mouse lineup offers customization options and unique features designed for medium to large hand sizes. The EC2 is a slightly smaller version of the EC1 and is available at a similar price. The mouse glides smoothly on mousepads thanks to its PTFE feet, and it also includes additional weights that can be inserted to adjust the weight. With the Razer Optical Mouse Switch, you get instant actuation and durability, providing a competitive advantage over traditional mechanical switches. The Viper is an exceptionally accurate mouse with a high IPS rating, making it great for quick movements. Its battery lasts for approximately 70 hours, and it comes with a convenient charging dock. The Roccat Kain 202 AIMO is a simple and reliable mouse that is perfect for gamers who prefer a minimalistic design.
