I have done so many transactions on ebay and my experience with ebay till date is great . Price on ebay are very competitive and their refund policy is awesome. Usually I go with seller having good reviews . I had only one bad experience where I got a refurbished item from the seller.
I send an email to ebay with the proof and I got my refund within a week .Based on my experience I can say ebay is safe and ebay guarantee is worth .Definitely it’s better than websites like homeshop18, shopclues etc .
