Bests & Worsts Reviews from Amazon

I've been a loyal Logitech customer since early 90s, but as much as I wanted to like this mouse, it's a big disappointment. Here's my assessment: Pros: 1. Feels nice in the hand, good ergonomics. 2. Can be used on all surfaces 3. Bluetooth. Cons: 1. Logitech is now switching to 1 year warranty? I wish I knew before I ordered. Here's why it's a big deal. Somewhere in mid 2000s Logitech switched to new type of microswitches in their mice. These microswitches fail after 1-1.5 years of daily use. How do I know? I have a box full (no I am not exaggerating) of Logitech mice with broken left mouse button. Every single Logitech mouse I had in the last 10 years developed a left (sometimes right) click problem. Every single one, and I probably had 10-12 in that period. I also have a couple of mice from early 2000s that still work just fine. This is not the quality I would like to see in a premium product but it was OKeish while Logitech had a generous 3 year warranty. I had each mouse replaced once or twice under such warranty. While it was inconvenient, I felt I got my money's worth. Now, with a 1 year warranty, paying $60+ for a mouse that will be dead in 18 months feels like a ripoff. 2. Mouse wheel press acts not as a third button, but to switch between ratchet and smooth scrolling. There is a button behind the wheel that can be configured as a third button, but the mouse wheel press cannot be configured as the third button. Really, Logitech? Whose bright design decision was that? This is opposite of the way every other mouse works out there, including other Logitech mice. I remind you, this is a laptop (i.e. secondary mouse). So the idea is I have to break muscle memory every time I switch between mice or laptop and desktop? 3. I thought we were way past loosing mice receivers or trying to figure out which one goes with which mouse. Even cheap 10 dollar mice allow you to store a receiver inside. For a travel mouse it's virtually a requirement. But in this new and "improved" model, Logitech decided to get rid of the storage compartment. Why? I am dissatisfied with the design decisions of this mouse and very sad to see where Logitech is headed with quality and and warranties. I will be returning this mouse and looking at other alternatives.
