Customers find the mouse well-made, comfortable, and ergonomically fantastic, particularly noting how it alleviates wrist and hand pain. Moreover, they appreciate its quiet operation, glove-like fit, and spot-on sizing options. However, the mouse's reliability and responsiveness receive mixed feedback - while some say it works great, others report it stops working after a day, and while some praise its responsiveness, others mention pointer lag issues.
