I also have the Galaxy S2 and have been "II i9100 Samsung ECR D1A2BEG Dock for Galaxy S" spoiled by the tailor-made and have been annoyed beyond measure, that there is not something like this for the S3. This original S3 loose bracket I did not, so I had them ordered in July 2012 here and use it daily without any problems since then to recharge and the "table service".
CHARGING TIME REDUCING TIP:
The original S3 charger use and plug into the USB port of the desktop charger (not in the "DC IN 5V"!) And have the Samsung quick charging is performed! - Controllable via S3 menu button / Settings / About device / status / battery status = "Load (AC)" instead of "Load (USB)" - I guess the "DC IN 5V" terminal at the dock only the current carrying two wires are passed through the microUSB socket, while the USB port and data to be sent, so there is a full wiring and the proprietary Samsung accessory detection via resistors works there and the smartphone fast charging with higher currents permit.
For processing of the supplied accessories's I can only add my voice to the other reviewers.
The charger has 1 Ampere and invites only the slow USB mode. The car charger is very warm and the microUSB contact with the smartphone is not good. The USB cable are inferior. The accessories are quite nice, but I use it rather not for my dear highend smartphone. For the car I have the original Samsung Galaxy S2 USB cable together with the "Wicked Chili Dual Quick Charger Car Charger Adapter (12V / 24V, 2100mA, 2x USB) for Apple iPad 1/2/3/4 iPad Mini and iPhone 4S / 5 black "in operation. Also battery status = Load (AC)!
To complete the desktop charger I had to also be artisan act:
Under the Dock are four circular depressions, which are intended for rubber feet that are not settled at the factory. Remedy bought myself a bicycle repair rubber, which I cut with scissors and glued with double-sided tape in these depressions. Now you can also press the Home button on the S3, without pushing the cradle off the table ... But it is also, if you stabilize the charging station with the middle finger behind his thumb presses the Home button. :-)
I forgive 4 stars for the desktop charger (A star deduction for the missing rubber pads). The rating for the accessory would be my only 2 star value. Since it is my opinion, but the only reasonable charging station, I give a total of 4 star.
PS: This is my very first review!
