We stayed true to the original Sensei\'s beloved ambidextrous shape: a blank canvas for however you hold your mouse, from browsing the web to winning the world\'s top tournaments. The iconic shape can be used by both left-handed and right-handed users, and supports claw, finger, and palm grips allowing you to easily find the most comfortable way to hold the mouse for hours at a time.Instead of the standard single spring, a dual spring mechanism increases durability and performance, ensuring a consistently crisp feel from the first click to the 60 millionth. State-of-the-art engineering allows for a mouse built with high-grade polymer that can withstand the most intense wear and tear. The material also maintains a lightweight form factor to reduce hand fatigue that is also structurally sound.Behind the NameTen is the Japanese/Chinese character for \"heaven\". The Sensei Ten is the truly ascended form of the classic Sensei shape, which was originally released in 2009. The Sensei now celebrates over ten years of excellence.
