I believe it is fair to say that most people who are new to vaping look for a Personal Vaporiser that resembles a tobacco cigarette as much as possible. I remember that I felt the same way when I was first introduced to these devices more than a year ago because I believed at the time that this would be an important factor for the vaping experience to be a satisfying one.
However, as one progresses, the desire for a device that resembles 'the real thing' becomes less and less attractive. I found out that in pratice it wasn't an important factor to me at all, what mattered was the amount of vapour, throat hit, flavour, how long the batteries lasted (this definitely moves you away from the smaller devices that look like 'the real thing' !), and the general sense of satisfaction the vaping experience of the device provided.
And now, with all the hullabaloo around possible bans and such, it has become even more important to move as far away as possible from anything that looks even remotely like a tobacco cigarette. I have found that when vaping in public, using a device that looks like 'the real thing' ultimately cofuses people and sometimes makes them prematurely negative to what I am doing.
That said, it is a personal choice and we all have the right to learn as we go along. Although what Agnes Peacock is saying may possibly be true (and not entirely convinced of it as there are enormous numbers of people on this forum who are new to vaping), perhaps the way in which it was stated could have been more nuanced and included a bit more explanation for the OP, who is obviously new to vaping.
Hope this helps.
Cheers,
Silver
PS: Forgot to mention; welcome to the forum New

! This is truly a great place with lots of wonderful and supportive members who will gladly help you as much as they are able to. I too have no experience with this particular device or Seller, but IMO Letzin Hales' suggestion is excellent, doing the research will help you make a decision. Hopefully someone will be along shortly who does have experience with this device/Seller and give you their opinion.
