I came in to a lot of money in 2012 so I used that as an opportunity to replace all my aging PC peripherals at the time with new, decent stuff
I picked up a Logitech G400 wired optical mouse which was an incredibly good mouse for the price (I think I paid $25). So good, in fact, that Logitech jacked the price up and now they sell for $60-$80 depending on when and where you look.
Basically, it just feels really nice. I’m not a fan of the extra buttons on the side (I hit them by accident a lot) but it’s got decent DPI settings and whenever I have to use lower DPI mice, I can definitely feel the difference in smoothness. I’m not sure how it would feel different from a G403, but there’s gotta be a reason the G400 is still (a little) more expensive, right?
Since my G400 is coming up on starting its sixth year of service, I have been doing more maintenance to the device in an effort to extend its longevity. Earlier this year the scroll wheel had stopped working, so following a Youtube tutorial I carefully opened the mouse and gave it a rigorous cleaning – I discovered that the scroll wheel mechanism is incredibly simple and designed not to wear out. The real problem is that 5 years of lint and crud had worked its way in to the device and was blocking the scroll sensor. It was really nasty, and by the end of the cleaning process, I had dug out a marble-sized ball of fuzz that had accrued in the corners of the device.
On the plus side, the mouse now works like new.
