What is the difference between Logitech M235 Red at 15.70 and M235 Anthracite at 23.85? What is the reason for the price difference? The description still says clickable mouse wheel - what is that good for?
The most important difference is the mouse sensor/surface scanning: The cheap M235 Red has optical sensing, the expensive M235 Anthracite has laser sensing. The laser is better if you have a shiny table surface or even a glass table.
Clickable means: When you scroll the scroll wheel, you can feel the detents. You can switch this off so that you can scroll smoothly. With raster you scroll digitally: i.e. 3 lines per click. Without raster analogue, i.e. line by line.
However, both M235s only have the digital version: i.e. clickable. According to the photo
Both M235s have a USB nano receiver. If you want to use the mouse with a notebook, you need a USB slot. These are rare on a notebook anyway. So I would use a Logitech mouse with a Bluetooth connection. e.g. the M650 The M650 is 10.5 cm long The M650L is 11.5 cm long
