Logitech M705 Marathon Wireless Mouse – Long 3 Year Battery Life Ergonomic Sculpted Right-Hand Shape Hyper-Fast Scrolling and USB Unifying Receiver for Computers and laptops Dark Gray

Customers find this wireless mouse to be of high quality, comfortable, and ergonomically designed with a very ergonomic shape that fits hands comfortably. The battery life is exceptional, and they appreciate the programmable buttons and fast scrolling feature. However, reliability and functionality receive mixed reviews - while some say it works well, others report it stops working, and while the scroll wheel is excellent, some find it erratic. The size also gets mixed feedback, with some finding it perfect for smaller hands while others say it's not meant for small hands.
