Good keyboard to substantial errors

I have now tested the keyboard 2 weeks extensively.
The first few hours I was very impressed by her, until the first error occurred and thus also a long search for the cause.
I found what I was then in the official Corsair forum where a lot of users on the same problems as I complained. And this is probably for several months, without which was rectified in any way by the manufacturer.
In my case, I am referring to software version 1.3.91 and to firmware version 1.15.
Here once the biggest drawbacks:

- Once the software keyboard is running together with Steam, freeze the lighting effects (sometimes the entire keyboard) a. Other users report that this would happen with Uplay. I have not tried it though. This may of course not happen in a gaming keyboard. And certainly not in the price range.

- Of the advertised 16.8 million colors are only 512 available. This bucking soft color changes (such as in a rainbow wave) very strong and you can every single color "jump" see.

- Sporadic it happens that the keyboard is not recognized by Windows Start only. Reinsert the USB connector does not help then. In my case, there helps only a complete restart Windows.

- Occasionally, the boot process by 2-3 minutes delayed. If you connect another keyboard to not have this problem.

That would be times been the really big problems that has this keyboard in my opinion.
This is a shame, because if the keyboard properly once Runs (Steam shut down PC multiple boot, just normal key illumination is activated) it's fun and makes visually and haptically her a lot.
However, I am of the opinion that the errors mentioned by me in this price range simply can not be.
Especially not with a gaming keyboard.

!!! All these errors were also officially confirmed by Corsair !!!

I'd like to wait for another driver update from Corsair, but before my return period expires, I will give them back rather.
