Hardware Secrets posted a review on the Gigabyte Aivia Osmium Keyboard

There’s no stopping the current “mechanical keyboard wave” that is taking over the market for gaming-grade peripherals. Gigabyte has just added a mechanical model to their Aivia line, the Osmium, which features USB 2.0 and USB 3.0 ports, audio connections and five macro keys. Let’s first describe it, and then analyze the product.

The Osmium is a robust and heavy keyboard, weighing 3.3 pounds (1.5 kg). What first catches the eye is the bank of dedicated macro keys (G1-G5) on the upper left side and the two wheels that control the illumination and volume. The wheels are both dented and illuminated.
