Only euphoria, then disappointment!

I would now like to share my experience with this set with you.
The reason for the purchase was the low price; Moreover, I have never been disappointed by Cooler Master, as set forth really great fan. Now from the PC MOUSE I AM COMPLETELY disappointed!

PRO: Keyboard
-Ansprechende (Quality) optics
-Angenehme Haptics

CONTRAINDICATIONS keyboard:
Illumination could be brighter.
-Without Lighting almost unusable

PRO mouse:
-Liegt Comfortably in your hand
-Great Optics
-dpi 3-step adjustable
-Good Gliding

Contraindications mouse: KO criterion
-Left Mouse button defective after 2 months use!

I have könnnen expect from such a brand like Cooler Master, that the quality is good.
I'm really disappointed. Rather invest a few euros more. My old Logitech mouse is even after many years of use still good!

So you save the set and puts rather a few euros more for something decent on it.

UPDATE 05/08/2014:

Cooler Master shows up very accommodating and I was able to return the mouse.
I hope the next mouse will last longer. Should this be the case, I'll go with the rating upwards; probably. it is easy have been a production error.

UPDATE 10/12/2014:

The newly replaced mouse makes more problems.

- Squeaks scroll wheel and does not always work
- Left mouse button sometimes loses its function
(If you want to select files very annoying)

The keyboard is ok. Everything works as before.

CONCLUSION:
2 stars ..... The mouse is the second time NG
Only the keyboard is usable. Prefer to buy another set. Very disappointing
