I was initially very pleased that Logitech again offering a convenient cable mouse with laser tracking that we can use in the production operation. However, the mouse brings a huge problem: The mouse wheel in the center is so sensitive that even a gentle touch triggers a scroll and thus interfere with the normal working process. For us / me the mouse is therefore completely useless. The Logitech Support has tried to explain to me that it is the product is a low-priced product and should not be compared with expensive mice. Please what? Even the RX250 for 7 Euro has a scroll wheel with snap-on function per scroll.
