It may have been voted the best handset by Hong Kong people. It could be the world's favourite MP3 player.
But, before you buy anything, you need to look around. Hong Kong people have a wide range of products to choose from.
First, you need to gather some information. You should find out how the product is different from others, whether it has better features and what's the best deal. Salesmen and the internet provide information. But you have to be careful. Their goal is to sell their products. Some information may not be objective.
They could emphasise one product feature, without mentioning the negatives.
You can also read testimonials from other customers. Some websites allow all opinions but others only post positive reviews. Besides, the customers are different. The one who wrote 'best camera ever, so simple to use' might only take pictures on holiday. You might want a camera to take pictures all the time anywhere.
It is important to make a list about what you need, what would be nice but not essential, and what you don't want.
