I actually do not write often a review, but due to these numerous negative reviews I want to share my experience with the Razer Taipan. First, I had a Microsoft Habu, which gradually ran increasingly rubber after 6 years, and the keys are no longer anfühlten beautiful. At first a short Eingewähnungsfrist was necessary because the Taipan is a bit smaller than the Habu. Once you get used to it, however, all this is no longer a problem. At the Synapse 2.0 drivers from Razer: even I was skeptical at first here, but I have to say is all totally uncomplicated. You have to register only with a valid e-mail address, personal data will not be retrieved. Here now was often reported that the mouse can be used only with an internet connection. And this point is simply wrong !! Yes, you need an Internet connection, but only for registering e-mail / password for the settings of the mouse in Razer cloud can be stored. Substituting even be new to Windows or want to use the mouse somewhere you immediately its usual settings at hand. With so much adjustment, which provides the Razer driver and the Taipan makes only sense! If one has made its settings and synchronized to the cloud, you can top right enable the driver to offline mode. An Internet connection is henceforth no longer needed and the mouse works just like any other mouse also. The quality of the mouse's top. Haptics etc. fits all. Of course, the device is expensive and you have to decide for yourself whether it is a worth that much. However, one should think that the mouse and keyboard are the interface to the PC, in my opinion, you should not save in the wrong here.
