The shipping cost is about US$4.15 (~S$5) via USPS (First Class Mail International Parcels). This shipping method is the cheapest but it is delivered via normal mail when it reaches Singapore as it does not come with a tracking number. Also my box is a little bit damage, but at just S$5 for shipping, I can’t really complain much. My item was shipped on 20th August 2011 and I received it on 8th September 2011 (about 20 days).
As the name suggest, this product is a dock that allows you to plug directly to Apple USB Power Adapter and dock your iPhone, iPod Nano/Touch directly to it without the need for any Apple Dock Connector to USB Cable. It is really good for travelling as often the power socket in a hotel room is always located at awkward position and you do not want to place your device on the floor with a wire connected to it as it is dirty and you might trip over it.
