I am using Redmi Note 3 and am very happy with the product and complete package.
When it comes to Redmi Note 4 the product is excellent and great but I feel MI India is misguiding potential potential customers to log on the website on a predetermined date and time very well knowing that the stocks are not sufficient, this is in away negative approach by the creating in creating negative demand.
I feel that such marketing strategy will be short lived and temporary, despite the fact that MI India has good products to offer and have a strong foot hold in the Indian mobile market.
