Ebay deals with second hand products also and have a large selection of products and customer care is reacheable but my experiance is once I purchased a metal mobile case but its damaged and twisted worstly because of their poor packing quality but however ebay refunded the amount after requesting to them also when I purchased a powerbank it also damaged so we contacted customer care and they refunded the amount.
They delivered on time sometimes there may be delay because of some problems and also product quality is good but packing is not that much good. It have some chinese products like sony power bank
