I was initially impressed with the cheap replacement for expensive original batteries because it's then been not matter that there was no note in the charging of the batteries when and if the battery is full or could give the controller information on the status of the battery and also that the processing but was quite cheap. The main thing is running. Well, also ran .. but only about half a year, the battery now lasts one probably a maximum of half an hour and when he gives vibration soofoort the ghost. Too bad, would have been so nice!
