Great keyboard. It's built as sturdy and durable as they come. Cherry MX Brown switches with O-rings for the quietest mechanical keyboard. Logitech has some solid products and this is definitely top notch keyboard that can compare to other high end mechanical boards like Ducky, Filco, & Das.
With any products your going to hear of the DOA's or issues etc. The lightning issue isn't wide spread but when one OCN member has two LED lights partially go out, it does cause for pause. Logitech did make good on their warranty and stood behind their product with successful RMA. I bought mine knowing of this LED possibility but Logitech's great customer service carries a lot of weight for me that I have absolute confidence. They even replaced our members modified board where he took it apart to color the orange macro border black. As for me, my G710+ has no issues as of typing this and I type pretty darn hard on my keys.

If your in the market for CherryMX Brown keys this board take this one into consideration. Also comes with nice little perks like USB port, one click Volume controls and volume roller. The macro keys have three sets of profiles with 6 macros per profile for total of 18 macro keys.

At first I thought the orange was a bit much and wasn't fond of it. After having it in front of me, it turns out it's not as prominent pictures made it seem. I solved it by pairing it with the SteelSeries Sensei Fnatic and I couldn't be happier.

Also first keyboard that I know of that has shipped with 'Windows 8' logo on Window keys on each side.
