Pros: -Great clicky action -Beautiful RGB -Solid feeling keyboard -Great to see keys in the dark

Cons: -Too loud for cubicle use (blue switches) -Not much brightness variation from low to high.

Overall Review: I love the feel for this keyboard. The clicky action is just right. Now I can't stand "normal" keyboards! I would not get this for cubicle use, it's just too loud, but that's what you expect with blue switches. The RGB action is awesome, and it's so nice being able to read the keys in low light. It's got nice modes for all keyboard functions. The brightness doesn't change much from low to high, but still a nice feature to have.

Pros: -Enabled great frame rate increase for Rocket League

Cons: -Huge size

Overall Review: My son bought this for his scrapped together computer (free). He ended up using an i3 processor and still had something like 130 fps on Rocket League in the highest video settings! He's very happy with it. The price seems pretty good for a 1660.
