Wonderful mouse, amazing customer service, but beware firmware issue.
Coming from a 120+ gram Roccat Nyth (great mouse with modular thumb buttons, and I used it in the wide setup for ring finger support), this is a light, joyful experience in the hand. I am using no additional weights. After watching Rocket Jump Ninja's excellent reviews, I decided this was the proper fit for my hands (over the Logitech g403 and SteelSeries Rival 310). It's easy enough to setup with the software (SteelSeries Engine 3), and the automatic recognition of games/programs works quickly. I have used both Roccat and Logitech software for programming mice, and they're all somewhat opaque at first. I think each need some UI work when it comes to selecting profiles to be edited. They all work well enough. The first Rival 600 I orderd was an Amazon Warehouse deal for a used mouse. It was like new and seemed to work flawlessly...but it had an issue that others have reported elsewhere online: the firmware would not load. Indeed, the software periodically became unresponsive, and the mouse sometimes failed to swap profiles. Additionally, when waking my PC from sleep or booting up, the mouse would not respond besides lighting up the LEDs (although the two middle strips were flickering noticeably). So after interacting with SteelSeries customer support through their website, they decided I ought to RMA it. In the interest of time, I returned the defective unit to Amazon directly and purchased a new one. It came with up-to-date firmware already installed. Now the software works great in concert.
