Vape is awkward to fill. There is a very small port and no where for the air to go as the juice enters the port. So it tends to run down the side of the vape. It is also awkward to engage vape, the activation button is on the bottom of the vape. I am accustomed to having the button the side of the vape. It is lightweight and fits well in your hand. I would not purchase a 2nd one.
