Please beware that there is no manufacturer warranty on any items on ebay.
Below given is what happened to me:
I bought one HTC desire 826 worth Rs 24999/- from ebay 2 months back. Just after 1 month that phone died. Stopped working. I went to service centre and they said that the bill is fake and phone is stonlen one or from grey market. HTC service center gave me in written that the phone and bill is fake one. On product description there was mentioned that product has manufacturer warranty.
When I contacted ebay, they said they cannot do anything as one month period is over. Now just consider a fact that even fake products work for a month and post 1 month there is no support from ebay. So if you are buying anything from ebay this is for sure, if the product is fake or stolen one, there is no chance you get any help .
I have proof on paper from HTC service center.
