The most reliable company is APPLE and I mostly used the products of APPLE. Recently I purchased a Mac book for me and a Iphone XMAS Pro. I know the prices are too much that's why people not buy products from Apple but for any brand whether it is Xiaomi, Samsung, OPPO or huwaei etc make sure to use Amazon promo codes that cut your price and get you more savings. I hope that would be a good advice for people who really want products in affordable prices.
