Dear pradeep6366,
ebay is present in 33 countries and millions of trades are taking place.
As far as receiving of goods is concerned ...you don't have to trust anybody........you have to trust ebay.
ebay is a mediator which provides trading platform and takes guarantee for upto Rs.10,000 under Buyer protection.
If you don't receive goods then you can file a claim with ebay.
Further...as far as the Quality of Item is concerned, you will have to apply your wisdom. I mean just check up few things.
1. Check up the Sellers feedback.
2. Read Sellers feedback comments (if possible for the same item)
3. Compare prices with other similar Items sold by different Sellers.
4. Better would be to buy branded products in the beginning so as to build up confidence.
ebay suggest some Buying Tips for New Buyers like you.
