Some people can not live without cells, whereas others think that they are harmful.

I think that cell phones are a good and useful invention. First of all, they allow people to communicate with lots of people without leaving their homes. Second, nowadays cells have become multifunctional, which means they are used as photo cameras, memory storages, payment systems so on. Having a phone let people get rid of many gadgets.

At the same time there are people who say cell phones might cause various diseases or mental troubles. There are phone-depended people who do not feel comfortable without phones. People also see each other less because of the mobiles.

I cannot agree with the opinion mentioned above for a particular reason. Cell phnes might be psychologically harmful for some people, nevertheless, the danger for health that  mobiles might cause has not been scientifically proved yet. Talking on the phone with a person is almost as real as in person, which compensates many potentially bad things that it can bring. 

In conclusion, I would like to say that any good invention can be turned into a dangerous one, if we misuse it. Telephones are primarily meant for communication, not for playing games on them all day long. I strongly believe if a person starts feeling dependent on his or her phone, they need to stop using it. Nevertheless, I consider cell phones  one of the greatest inventions ever.

In conclusion, I would like to say that there are opposing views on this issue. At first sight cell phones might seem harmful but in actual fact they are a great invention that unite people and make their lives easier. Thus, I support the idea of using mobile phones all around.
