Logitech M650 L. The old medium size is the new large.

Logitech Signature M650 L is a wireless mouse with a Logi Bold wireless receiver. It has silent keys, which, unfortunately, require too little actuation forse to click them. I've owned an old Logitech mouse with Silent Touch technology, and the keys on that one did not click so lightly and sounded just as quiet. It is very dificult to rest the finger on the right button, as it keeps clicking. The left finger is shorter and applies less forse, so the button does not click acidentaly usually.
After reviewing my little rant, i added some angry music to make it even angrier for fun. Please don't take it too seriously, as your experience with the mouse could be different form mine.
