Pros: Quiet, pushes a lot of air. Looks great.

Cons: I ended up using rubber push pins to mount the fan. The included screws weren't the best

Pros: Beautiful keyboard. Very solidly built. Decently small footprint. Just looks like a work of art. If you never play games and are not concerned about key ghosting, then this keyboard is the best I've ever seen, even for the higher price.

Cons: If you ever play games, this keyboard will fail you dramatically. I have used "non-gaming" keyboards for 15 years and have never experienced the problem this keyboard poses. It has ghosting/key lock bad!!!!! For example, most games require you to press "w" to move forward. You might also need to press "shift" to run. If you try to press another key on the left side of the keyboard while pressing W and Shift keys, like "space", FAIL. After searching the web, there is no fix, period and Logitech does not feel like they need to address it in a future revision.

Overall Review: I'm really disappointed with Logitech. I've used their products for years and years. I think they made a poor design choice to save some money, didn't think anyone would notice. We'll from plenty of postings online, people are definitely aware and it will give me great pause before purchasing a Logitech device again without extensive research prior. Luckily Newegg has an amazing RMA program and I was able to return it and purchase the microsoft sidewinder keyboard which works great.

Pros: - Looks pretty cool - Very Accurate

Cons: - Succumbed to the double click of death after about 18 months - I'm not a super heavy user, not a big gamer and this thing still bit the dust on me. Pretty disappointing. - No way to repair either.
