Electronic individual supervision good price

For the price (15) ok. The device seems to recognize to what a battery (NiMH, NiCd) is, and (not unloaded are an advance, the other) fits ebtsprechend the charge on. There is a slight hum of itself loading, on the bedside table, but I would not make it anyway. In the previously charged batteries, the device was completed faster than expected, we'll see how long does the charge. Drawback: No test function built for ordinary batteries because immediately comes the message "Charging error" rather than to show "full".
