Speedlink: Omnivi Core and Kudos Z-9
Speedlink is primarily active in the budget segment, but also has some mice that are slightly more expensive. The Omnivi Core and Kudos Z-9 both cost about 70 dollars. They use not further specified laser sensors. The Kudos Z-9 has a maximum of 8200 dpi, while the Omnivi Core goes all the way up to 12,000 dpi.
The mice have a bright red colour. The difference is mainly in the build. The Kudos Z-9 is a relatively small mouse with an ergonomic design, although the bump that functions as separation between your ring finger and little finger does feel slightly unnatural. The Omnivi Core is a bigger mouse with a lot of extra buttons, both on the side and at the top. Unfortunately not all buttons are easily pressed.
In terms of speed we are satisfied with the sensor of the Kudos Z-9: the mouse should definitely not be ashamed of more than 4 meters per second. We do measure consistent acceleration. The lift-off distance is about average. The Omnivi Core shows the same speeds, but this mouse does not have acceleration and a lower lift-off distance. However, for low-sense gamers it is not suited, as the grip is not enough for this type of use.
