30-Pin to USB Female OTG Cable for Samsung P7310 / P7300 / P7510 / P7500 (7.5CM-Length)

Pros: Decent build quality. The 30 pin connector fits my Galaxy Tab 2 7.0 just like the factory supplied connector. This is a good thing since not all the connectors fit well. Some are such a poor fit that it seems they will damage the tablet. Not this one. It is also superior to the direct plug in OTG (On The Go USB) modules in that it will help prevent damage from being hit since it doesn't stick out the side of the tablet much.

Cons: No cons on this part. It works and is well priced.

Other: Buy it or buy three. It does what it says it will do with much reduced chance of damage to your device.

Pros: I wanted to use this on my Samsung Galaxy TAB (P7510) for some time, but the official one from Samsung was too expensive. When i saw this, i bought it immediately. It work great and now i can connect many USB devices to my tablet to transfer files to and form it without the need of a computer.

Cons: Apparently, some usb flash drives are recognized but then are automatically disconnected. Its probably a power issue. I havent had these type of problems when connecting mi digital camera to it, as the camera has its own internal battery as power source. Forget about connecting external hard drives unless you can provide external power for them

Other: For this price, do yourself a favor and get it, you never know when you are going to need it.
