Review title: Overheated charging first set of batteries
Product review: First use of the product charging 4 of the supplied AA batteries on the 400mha setting. After a couple of hours, I noticed that 2 of the selection buttons, 2 and 3 where sitting low as if they were depressed. I removed the back and the main board and saw that the charger gotten so hot that the end of the buttons melted! I believe it is because of poor soldering of the battery connectors of slots 2 and 3.
