Performance

The Argon Ocelot World weighs around 94 grams without its weights and cable. Include all the weights and it'll weigh 112 grams, which will make it very rear heavy due to the extra weight in the back. This leaves the mouse significantly harder to control than if the weight were distributed evenly across the front and back, which makes these weights seem more like an attempt to fill out as many check boxes as possible on a features list rather than a way to including some extra functionality.

The left and right mouse buttons have a very short travel distance, but are slightly stiffer than the buttons on all the other mice I've used. The scroll-wheel click offers very little resistance, which is good because it prevents you from accidentally scrolling when trying to press it. The side buttons are rather mushy before they reach their activation point at which they give a very sharp click similar to that of the left and right mouse buttons. The two top buttons behind the scroll wheel are by far the quietest and hardest to press on the mouse. The one closer to the scroll wheel still gives a sharp click; however, the one behind it is muted and quite stiff, making these the slowest buttons on the mouse. The scroll wheel is lightly notched, so scrolling is light and responsive, but you can still scroll by exact amounts from these notches.

The shape of the mouse, combined with its rubber side grips, makes lifting the mouse up very securely possible since the mouse will not slide out of your hand. After taking some time to adjust to its ambidextrous grip, it actually feels very comfortable, and at no point of using this mouse for well over 40 hours did my hand feel tired or cramped. My hand being as big as it is, I used a very relaxed claw grip that is very close to being a palm grip. I expect most people to palm grip the mouse since I only claw-gripped it due to my finger tips extending almost a centimeter over the mouse with a palm grip.

The sensor is an ADNS 9800 from AVAGO. It tracks at up to 150 IPS and supports a maximum acceleration of 30G. The sensor does suffer from acceleration, but tracks well on all opaque surfaces.
