Very well made, works as advertised! With a quality, thick power cable USB 3.0. One small remark: the AAA Ni-MH and D-sized batteries will need a little adjustment to fit properly in the slots. One is too small, the other is too big for the "+" side of the slots. If the "+" metal plate was made just 2mm longer, it wouldn't be a problem at all! The D-sized battery I used in the pictures is only for example, as I don't have a 32650 Li-Ion one. Overall: very good, I would say excellent price/quality ratio!
