any services/products that:
- massively advertised, in online and out of home;
- send me a SMS or chat without my consent.
and by my experience, somehow underrated products (not massively advertised) are being good and have high quality than the massively advertised ones.
its because they're (underrated products) focus and investing most of money on the quality, than ones focus and highly invested in marketing, to manipulate peoples mind to buy the product.
