another feature I am going to look at is the customer reviews. Customer reviews are when a person who has the item you are thinking about purchasing give their opinions on if it works good and things like the picture quality and suitability etc. This helps the customer by getting more knowledge about the product then they knew before. In the picture below I have put a red rectangle around some reviews which I found when I was looking at a Samsung galaxy ace smartphone. However there is a negative to this, because customers can post reviews maybe they will post a review which has offensive comments or a comment with bad language in.
