I ordered an LCD assembly for my GS II I777 from etrade supply.

I had a very frustrating experience.
I received an assembly that was broken. One of the ribbon connectors was broken off. The ribbon was not adhered to the housing and the ground for the haptic buttons was not adhered as it would be on an OEM assembly.
I decided to return the part. Their return policy is that the customer pays for return shipping even if they send you a defective part and they verify it. Since they are based in Hong Kong shipping is expensive.
They verified that the part they sent was defective and credited back my original cost, but left me out to dry when it came to the return shipping cost. I declined to have them send me an additional part because I was afraid I would get another piece of junk that I would have to pay to send back. They did offer me a coupon for further purchases to ease my pain, but I will never use it.
In summary, I will never buy from them again, nor would I recommend them to anyone.
