The Original Kova has been around for about a year and a half and was quite startling when it was first released. The combination of a great sensor, ambidextrous usability and driver-free customisation were a unique combination.One of the biggest downsides of it though was the various button combinations involved to change DPI settings or colours. Without any obvious feedback it was a bit poke and hope at times and once you got the mouse dialed in to your liking you were loath to press anything.Now, following the successful "Plus" update to the Kone, it's time for a Plus, or more accurately [+], version of the Kova.That seemed like the perfect opportunity to take look at what's changed with one of our most used rodents.
