Dear Friend, I am 100% agree with you, I also bought one iPhone from EBay, after one and half month mobile touch screen was not working as earlier and the battery backup is even worst then worst, once you charge mobile fully it will work maximum Half an hour in the field. I will also suggest to the people Before buying anything on e-bay you must understand that the quality of most of the products may not be up to the mark. At the first instance, the products looks excellent, however after a few days they become partially/fully defective/unusable. If we put negative feedback then e-bay court dismisses based on the voting (majority of the voters seem to be sellers). This is based on my experience, wherein, several products became partially defective/unusable especially electronic items (touch screed mobile phones, TV/projector mobile, spy cam,CCTV cam and inflatable 5-in-1 air sofa). It is difficult to find time to follow-up the sellers for rectification, as some sellers tell lies. SO, decide carefully before buying. I know that e-bay will reply to defend, but truth cannot be neglacted.
