As I said it is good and it looks nice but there are no instructions so you can easily think it doesn't work - which I did. The thing you need to do to start it is press the button on the battery 5 x's to make it go on. Also if you don''t know much about filling the tube with juice you may have a problem there too. INSTRUCTIONS PLEASE! I have been using various vaping devices for 3 years so I know this stuff or can figure it out - you however may have more trouble.
