Electronic Cigarette

I tried to solve the problem of e-cigarette in the form of a venn diagram.

We designed a new type of e-cigarette. E-cigarettes are used by many people today, but there are many difficulties in managing them.
‘Venn’ is a new type of e-cigarette that is easy to use and manage.

Electronic cigarettes should be cleaned regularly, but they are not easy to clean. In addition, the majority of users purchase and use new e-cigarettes rather than batteries because it is difficult to replace batteries. This is inefficient in the use of e-cigarettes.
