This had, however, be done after approximately 2 hours. It is really good in your hand and glides without scratching beeen Mouse or without backing beautifully smooth. You get used to really fast on the keyboard and by now 2 weeks I do not want you to miss. The side keys are rubberized so you can not slip off. By wedge-shaped arrangement of keys you always know on what key you are currently in.
Qualitatively, I can only praise the mouse. Really well made and the shortcomings of the previous speaker, I can not understand. The mouse wheel is indeed smooth but not too smooth and with my mouse there was no chemical smell mouse. The drivers and the software, I can say that you can manage the settings even with school English.
All in all I'm very excited and can recommend them to anyone. Price for what you and they need to keinstenfalls before the more expensive models from Logitech and Razer hide.
