I have the charger now for a week, it loads really fast the Accu's from my SG3 on. Previously had always problems with the original chargers from Samsung, a charging time of 12h. and more was not uncommon, sometimes achieved overnight even only 70%.
The charger of Rydges invites my Accu now in 2,5 - 3 hours at 100% and the Accu holds depending on usage even back up to 1.5 days ... super, am fully satisfied with it.
From me a strong buy recommendation !!!
