Varieties of electronic gadgets, without which some of us can't live, come into being. Despite their conveniences, they bring people much stress, so people have to balance their advantages and disadvantages before buying them.
I can't agree more with the author. With the development of science and technology, more and more fantastic electronic gadgets come into being, which dazzles people. People can't resist the temptation to buy and update them since these gadgets become outdated too quickly.
I have a lot of favourite electronic gadgets， one of which is a video MP3. As well as carrying my favourite music， a video MP3 player can play up to 150 hours of movies and TV programmes. However, it cost me 2，000 yuan. Besides, the loud volume will damage my hearing if I overuse it.
