Ebay is one of the largest network of online shopping. Ebay is open for anyone to sell anything. Ebay is very cheap and doesnt always contails original products. But if the product is duplicate, we can know because its written. So we cannot say that its a duplicate site. I personally have ordered many electronics from ebay and all have a very good quality. Shipping take more than a week and sometimes more than 3 weeks. Some sellers send in less than a week. Actually thiw depends on the location of the seller and the location of the buyer. Overall Ebay is a good site, you can defininately order from it.
