Since I have this charger, the charging of batteries makes me almost fun. The practical display gives information about charging time, charge current, reached capacity, voltage, and more. There is always something to see during the charging process. The various charging programs are set easily and bring some startling results. The supplied batteries I had, for example after the first charge attempt (just 300-600 mAh were as capacity reached) written off as defective. After an extensive refresh program the charger from the battery, however, has an average out tickled 2400 mAh, so that they can now be used without any problems. I was also surprised the manual, which is just and understandable. After a few minutes, you can operate the device. If you also would like to make a point of criticism, could be called the I think something big delivery. A carrying case for a loader I really do not need now. Even a 50 cents lower price would have been better. But what does it matter if the device still is so cheap?
Overall, the BC900 has yet casually deserves 5 stars. A more perfect charger I can not imagine at the time.
