Compared to more expensive mice unnecessary frills was mainly saved: The mouse B100 comes in a minimal package, without manual or software and does not have any extra keys, so only the basic equipment. This is perfectly adequate and compared to nameless cheap mice this product is a good choice. The optical mouse has a red LED light and a sensor that works fine on normal tables and gaming surfaces, according to the prior art 5-10 years ago.
Currently more expensive mice work with more modern optical sensors and lasers for example, can use it to work on very different, even difficult dark surfaces. In addition, these high-quality alternatives are faster, ie who is playing a lot or used a very large monitor (> 24 "), is thus better served. And you can also laterally (horizontally) scroll. Who is the ten euros more worth, for example, should the Logitech LS1 Laser Mouse Scroll Wheel make coconut. For around two euros more, there's the Logitech B110 Optical USB Mouse variant optical USB 3 buttons + scroll wheel 800 dpi black that can scroll sideways but bumpy indeed.
For much more money you get wireless radio mice, which can move better and significantly better scroll options. Who get used to it, to be able to scroll with a finger swipe through large documents in all directions, is no longer happy with a simple scroll wheel. My favorite is the Apple Magic Mouse. Similar Touch Mouse from Logitech and Microsoft, I found the scroll performance disappointing, too unreliable.
