Held unfortunately only 3 months

My last keyboard of Lenovo I bought in 2007. This Tatatur held total of 5 years and made me very happy. This keyboard of the same type but smelled very beginning quite different and the haptics felt no longer high. After three months, then came even death in the form of ghosting par excellence. When the pressure of the Enter key, these responded either not, or much worse: too often! Then there was all the words in sentences, whose letters were all among themselves in a new line. I can not explain it. I have now bought another keyboard and the problem no longer occurs. Tested on another computer, the error occurred again.

Was once a great product, now no longer ...
