I order electronics and other items from amazon. Recently I bought asus zenfone 3s max. The product was new and I have no doubt on the genuineness. The order always come a day before the written delivery date.
I havent recieved any defected or damaged product so far. Returning of products is simple and they give ample gap to return it. Pickup is done at the sites behalf.
Earlier I had ordered iphone 6 and boat headphones as well. I want to share that it is best for electronics and avoid it for using it for foorwear and apparels.
