HI, I have recently experienced amazon.com and I would say. it is not a good website for indian users. as I was recommened some products by my friend who lives in america. the product was for the$50.(approx). and having added delivery charges. it cost me$90. exclusively of money changing taxes.
Customer service; not sure because I have not used it for no reason I would not say it is bad so I would it is good.
Product quality; product quality was good as it was genuine no scrap was delivered.
Delivery timeliness; of the company is good it reached in time as it was expected
Application; I would application is good because it is not as good as other but everything I would suggest to for the indian version of the site if you are in india.
