Hi,
here is my battery case, ordered from ebay:

Just got the same one.
The case feels so light that it's almost a cheap feel. While I wouldn't trust it if my phone fell, it doesn't really add to the weight of the phone. Charges fairly quickly so no complaints there.
For 20 bucks US, not too bad really.
