Great charger it is rubber and compact works great and you cant beat that price shipped fast and works amazing im glad i purchased this item this charger works flawlessly on both of our samsung devices however it does not charge through an otterbox defender case

Not a deal breaker in my book as this was purchased primarily for my better half

With the docooler s i9300 qi standard wireless charger charging receiver tag its doing a great job of charging up my phone every time i put it down

i have one disc toward the top of the case and one toward the bottom leaving the middle where the battery is uncovered except by the case
