I wish products would just give up on these rubberised materials. They always turn to goop over time. Unless it’s a part designed to be easily user replaced, just stick to hard plastic.

Huh. Haven't experienced that myself, having used a Master MX for several years (now in use by my wife), a VX Revolution for a few years before that (now my son's backpack mouse), and a Master MX Vertical most recently. My son has gone through several other Logi mice as his primary mice, too, but they've died of either worn out switches or feet (he's an avid gamer).

Not trying to invalidate your experience -- I've see with my own eyes a similar thing happen with rubberized coatings on laptops & keyboard wrist rests (other's not my own).

Just putting it out there that it's by no means the universal experience.

I use the g305, and have to replace it roughly once a year because the scroll button eventually stops working. I've been through 5-6 of them. Regularly on sale for around $25.

Wish I could find a better mouse I like as much as this one that I didn't need to pay a yearly subscription for. It's just the right size, lightweight, wireless, and being able to store the customizations to on board memory is nice.

not unique to logitech. This happens with my steelseries mice too. I have to clean them with alcohol or something.
