It cannot be any faster.Īttention! High port sample rate generates a heavy load on a CPU it's up to 15% in case of Pentium 4 3 GHz! That may be the reason why some people are not satisfied with this mouse in resource-intensive applications, especially in games. The sample rate was quite stable, it went down only when the mouse was moving slowly, there were no unexplainable abrupt drops. We most likely failed to move the mouse fast enough to reach this limit. According to MouseRateChecker, it varies from 700 Hz to 800 Hz. USB sample rate was set to 1000 Hz in the driver, and it was higher than 1000 Hz according to PS/2 Rate. The mouse lies tight in your hand, when you do it. The sensor still works when the mouse is lifted by two-three millimeters, so it's not difficult to lift the mouse off the table without moving the cursor. Precision and smoothness of cursor motion is up to the mark. However, the mouse works well on a mostly green Verbatim pad.Ĭursor control is very accurate, I don't have any gripes with it in games or in a graphics editor. Just like the first version of the MS IME. I managed to fool the sensor even with a black desk surface. Friction is low on smooth surfaces, cloth and rough surfaces increase friction, so you can choose an optimal surface for your needs. Mouse feet glide perfectly almost on any surface. I also had to play games with this mouse to evaluate its target functionality. I used this mouse as the main pointing device for two weeks at work and at home. It often involves much trouble to obtain your warranty from the manufacturer, if your retailer's warranty is over. Although they have no right to offer a shorter warranty than the manufacturer, it sometimes happens, so you should be careful. You should make sure your retailer supports this warranty.

We had no problems with flashing new firmware following directions in the manual. The logo on the back will flash to indicate the process. Besides, you can use the Apply button to save all settings automatically into mouse memory. It would have been great, if you could easily switch between profiles and see the current profile.Ĭonfigurations can be saved into a file and then restored. Cursor speed and precision can also be configured separately for each profile. Or for a graphics editor, surfing Internet, editing texts, and playing music. It would have been better to be able to adjust it at 100-200 dpi steps.Įach profile has its own settings, so you may configure profiles for different games. The choice of resolutions is small - just three options: 450, 900, and 1800 dpi.
The bundle includes an oval user manual with a driver CD and a certificate.
There are a lot of labels on the box, plus full specifications of the mouse in eight languages. You cannot try it in your palm, because it's surrounded by a high collar.
The traditional black box, decorated with a photo of the bundle, contains a mouse in a blister under a flip cover. It was engineered for network battles to be used with low sensitivity settings to movements (for snipers). Let's find out what's behind these words.ĭeathAdder is an ergonomic mouse for right-handed users, designed for any games and other applications. Driver with tweaks to reveal the full potential of the controller.Long, lightweight, non-tangle cord with a damper at the mouse case and a gold plated USB connector for maximum conductivity.Zero acoustic Teflon feet for smooth motion over any surface.Ultra large non-slip mouse buttons, tactile response design.Excessive maximum speed and acceleration that can be processed by the sensor.16-bit data exchange channel with a host.Maximum USB sample rate, up to 1000 Hz, so the response time is reduced to 1 ms both for the cursor and buttons.Maximum sensitivity, 1600-2000 dpi and higher.That's what the company declares about its mouse-making technologies: Nevertheless, various approaches give users a freedom of choice, so we are pleased to see any steps in this direction. Especially as it's not the only gaming mouse of this shape. It's difficult to say why Razer designed "a new improved" replica of Microsoft's Explorer.
