I needed a mouse for my work PC, and this one is perfect for that. Small, light, able to operate with only one or two LR6 batteries, and very enduring. It's been over a year since I served on average 7/8 hours per day (excluding weekends and holidays), and I still have not changed the batteries.
I find no weak spot him. Moreover it is Logitech, I devices at home that have nearly 10 years and still work ... It's always good to have confidence in his gear.
