Hi, ebay Feedbacks do reflect a Seller's reliability but there's a catch too. You need to check the Seller's registration date to ensure that he is selling for quite sometime on ebay and has around 100% positive Feedback score. Also, just make sure that he has not SOLD or BOUGHT tens of low value Items just to collect positive Feedbacks. There are Sellers who invest few hundred rupees in buying & selling Items as low as Re.1 and then fool the Buyers by selling high value goods like laptops, mobiles etc. by show-casing their high Feedback score.
