A sensor is the heart of your mouse. It can make a significant difference by determining its accuracy, precision, and responsiveness. A high-quality sensor can provide pinpoint tracking, ensuring your cursor moves where you intend. In gaming, it can mean a well-aimed headshot rather than a trip to the gulag. It can also deliver consistent performance across various surfaces, minimizing tracking issues. Additionally, a quality sensor often offers adjustable DPI settings, allowing you to fine-tune sensitivity to your preference. Today’s top brands provide high-quality sensors, even in more affordable models.
