Generally I like many things about this product including it's body.
Compact size will give customers easier to move around carrying it in pocket. Also, size of tank is more than enough for 1 or 2 days use.
But I found out that the coil burns too quickly. Although, the company's webpage argues that it will lasts like 3 months use. I felt the burnt taste very soon even after I replace the cotton maybe when I used the first coil almost a month.
