Vortez tried the SteelSeries Rival 700
A quote from the article:
Leaping to the opposite end of the spectrum after having a hands on with the Rival 100, we finally get the chance to play with the Rival 700.SteelSeries Rival 700 Review @ Vortez
At first glance it would be easy to dismiss it as a run-of-the-mill teardrop shaped mouse. Then on closer inspection, the subtle ergonomic shape comes into focus. You then see the different materials for the main mouse buttons and the rear shell. At the side you will find three buttons with an orange tactile bump for your thumb to rest between them as well as a fully customisable OLED display that is capable of displaying 128x36 animated GIFs at 10fps. This can also be used to display in game statistics and events. Pushing the Rival 700 beyond competitors, SteelSeries have implemented a tactile vibration alert. By making the pulses vibrate up and down rather than left/right ensures it doesn't interfere with the sensor tracking. The vibration can be customised to give various signals and alerts in game, E.G. in DOTA 2, it would repeatedly give a slow pulse if you are below 20% HP, or it can give a short sharp vibration to let you know once an ability has cooled down.
