Update;
The V9000 set arrived and I've had a chance to tinker with it. Here's the review I left over at Amazon;
While this KB&M set isn't going to win any awards, it's good for what it is. The keyboard LED RGB lighting is solid, the keys are comfortable and the extra key work as they should. The volume knob also works well. The first downside to this keyboard is the power button on top and center. It is WAY too easy to accidentally press. As the design keeps it very tall, such a button should be more recessed so it's easily accessed but not easily pressed by accident. I have have modded that button to be recessed and nonfunctional as it was not the key feature I required of the keyboard. I also removed the ugly green paint as that button should have been white like all the other keys. The second downside to the keyboard is a simple one, RGB lighting settings are not saved after a reboot or being unplugged. This can be very frustrating if a custom lighting scheme is desired as it will need to be reset everytime you power on your system. Third is a minor complaint, the volume knob should be further up near the right corner of the keyboard. IT works fine, but kinda needs more room by itself for finger and thumb gripping space.
The mouse is also solid and the DPI settings are good. The main problem with this mouse is that the RGB lighting on the mouse is not user controllable. The scheme set in the factory is what you get. It's not ugly, but not what I would like.
For the price paid the complaints are minor and the performance is good. Key performance is perfect, as is the mouse button clicks. The anti-ghosting seems to work exactly as it should. However, the makers should take note of the problems discussed here and resolve them in a future revision or version of the set, even if such changes raise the price $5 or $10.
See photos below;
Stock photo. Note the ugly green power button center keyboard. It is that ugly and it stood that tall;
I performed surgery to resolve the problem. Here's what that button looks like now;
Here's the left over bits from the operation. The keyboard had a microphone for one of it's lighting modes, which didn't work very well. It was removed;
Lighting in the dark. The colour scheme is a custom one set by me;
Now in the light;
As you can see, the power button is no longer in the way and while looks conspicuous by it's presence, it fits in with the rest of the keyboard. It was rendered non-functional internally by taping over the contacts on the membrane.
Now for the mouse. I performed surgery on it as well.

And after showing only steady red;
Leftover bits from the mouse operation;
As you can see, it had a weight. Not a fan of weighted mice, so I removed it. To get the mouse to stay on one colour(red) I cut traces and wired the up the 5v USB line directly to the input line to the red part of the multi colour LEDs(it has 5).
Going to do the same to the keyboard tomorrow as I want the LEDs to come on and stay on in all red. I might wire up the side in green & blue like I've got shown in the photos, but not sure yet. Either way, when power is applied, the lighting will come on and stay on in the scheme I choose regardless of what the LED controller is doing.
UPDATE EDIT;
Having rebooted my pc this morning, I discovered that the keyboard does in fact remember custom lighting settings, but you have to select it after each power cycle. It would be nice if it defaulted to the last setting selected and stayed there until instructed by the user. However, this is a minor annoyance. The keyboard is a joy to type on so it's an annoyance I can live with until I get motivated to replace it.
