I can only say -> "absoulte buy recommendation"
The advantages of this article are clear:
+ External Power Connector or USB to the PS3 (both ways)
+ Beautiful design
+ Stable maintenance of the controller in the charging device
Cabling + No tiresome to charge
+ Clearly color-designed LED lighting per platform (Blue - is charging, green - has been charged)
- Lightweight
The Smart Charger has a fairly light weight and therefore have to be partly held as the cradle otherwise with lifts into the air when undocking of a controller.
Conclusion: a top part which none of the more than one controller is missing. I already think about a second to create me.
