As name Amazon it is amazing . Most of the time products are always available . Returning at time . Product come as shown in picture , no frauds, no delay in products . I use most of the time . Personally saying site is amazing. Sale is on always there. Availability at rare places too. App also work so handy. It works on 2g, 3g, 4g, wifi too. Sometimes money when refunded it get delay . If you exchange something not as your expectation thing comes . This thing makes Amazon a not good site.
