The Corsair K55 RGB is a decent full-sized gaming keyboard that uses rubber dome switches, which don't offer the same tactile feedback as mechanical switches found on most gaming keyboards. It has six extra macro keys, and since each key is macro programmable, you can customize it to your liking. The keys are stable, but they feel heavy to type on, and you may experience fatigue when typing for long periods. It has zone-lit RGB backlighting if you want to use it in the dark, but you can't change the lighting on a per-key basis. It should be fine enough for casual gamers, but it might disappoint some more serious or competitive gamers.
