Been using one for almost 10 years.

It's convenient, but most important of all, when the clothes are all dried up, while still hot, if you hang your clothes up, you won't need to use an iron anymore.

Haven't used an iron in years.

Having said that, the cons are it costs money to buy and operate (electricity). It's your money, so I am not in a position to tell you how you should spend it.

Some people spend it on cars, some on clothes, some on convenience, some on hobbies. Different people different priorities.
