I bought the nitecore UMS4.I live in France. I was afraid it was a fake. I used these 2 methods to identify a real fake: https://www.nitecore.co.uk/Blog/Post/16-identification-guide-for-nitecore-charger-users.htm " Place the magnet on the metal surface (battery positive pole contact points or slides in the slots) of the charger. A legitimate Nitecore charger does not attract the magnet, while a counterfeit charger does the opposite. " -and i confirm that my magnet was not attracted at all by the positive pole, thank you banggood for your seriousness! but to be really convinced of an authentic i made the 2nd method: Disassemble it.It is very easy :) -and i was really reassured to see the 2 capacitors with write on : NiteCore! I post my photos, i think the rest of the components are authentic too thank you banggood I recommend !😛😛😛 sorry for the poor quality of my photos

The charger is well designed, multi functional and supports wide range of batteries. It displays live relevant battery and charging information including Equivalent-series-resistance, indicating battery health. The build quality is very good, the buttons tactile feedback is definitive and the menu settings of each battery can be accessed and set with ease, very intuative.

Very good product. Like it because now I can charge my extra long 21700 with protected circuit which got an extra length due to the circuit board. Believe it or not there is still space left.
