Summary: Just adding this as a warning for anyone that may be thinking about buying one at a retailer that still carries it. Stay away, there's a reason they discontinued it. Too bad though because otherwise it would be a great product.
Pros: Great keyboard feel, trackball works well, good range, looks nice.
Cons: Wireless dongle very fragile. The first one failed in a week or so. I thought it may have been my fault so I bought another keyboard and treated the second dongle with kid gloves, it still died within a week. Got that replaced under warranty and carefully glued the metal part of the usb connector...
Summary: Be aware that this keyboard is a re-badged Zippy/Iogear and that definitely means you should be aware of the trackball issues.
Pros: Very good looks, rugged build quality, excellent key response, perfect scroll wheel, great range.
Cons: The scroll ball could be a little more refined. It tends to be a bit sluggish at times, and not as graceful as I had hoped, but does get the job done. This keyboard would be perfect if the scroll ball was a bit tighter. I would have given five stars had it not been for the scroll ball.
Excerpt: If you are looking for a sleek keyboard, then the Enermax Aurora may be for you. It’s built with aluminum for a strong frame and uses the same technology behind laptop keyboards for ultra-quiet and smooth operation.
