I want to share my experience with swiftkey keyboard .
Initially when it came in the market it's craze was there so one of my friends bought it from the Flipkart , and it was working properly so I also thought to get it and I also ordered it from Flipkart , I could used this only upto two months even I was using this only one or three hours per day , now situation is that you can't press the some key , and suppose you have pressed then it will come out of these that key will be being in the pressed conditions , some times key comes out of board , and sometimes automatically disconnected from the setup.
