The Krypton is well made, looks chic and glides very well and quietly about my Scheib table (not as dreamlike as the Mionix Naos 8200, but also costs 50% more). The scroll wheel is a dream, the actuation thereof to trigger a middle mouse button while needed for my taste a little too much power, but is just. Have relatively small hands, everything is easily accessible. The cat humped shape is not my thing, find it in the long run not ergonomic, but would I be able to get used to it. An absolute Nogo for me were the other hand, the slight release of the left and right mouse button. I switch between Palm and Clawgriff in two conversations my fingers resting lightly on the keys. Now, when I pan-actuated left or right, it happened again and again that I caused unbeabsichtgte mouse Klickts. What was just annoying and annoying while surfing, resulted in shooters repeatedly to the virtual death. Therefore, I had to send it back, unfortunately. Thanks Amazon, for this customer-friendly service.
