Ditto thats exactly the way I feel.First, FT is a clearing house much like Amazon. Somethings they have on hand, somethings that have to call the factory for. Odd that it is, there are different factories making their own version of the same authentic. Again, sadly they don't like to say what factory is making it, so getting a reading on the factory is hard. For me, I read the reviews and the discussions, all of them. I also look for SKU numbers and any reviews/opinions posted on forums.
With all that in mind, I haven't had much problem getting a decent product, it just takes time and effort.
I also use 3FVape. I just received 6 KV5 toppers. I have three cleaned, parts reviewed, built, and filled. They seem to work smoothly, no leaks...I don't know about the other popular clones for the KV5, I just got these because 3F seems to look for better clones to put on their site. 6-7 purchases with them now and always good. Cost a little more, though. Travel time is about the same.
As an overall experience with clones, do the homework and you'll get a better clone. I do have some authentic, but if I work for good clones, I can get 4-5 toppers for the same cost. I don't do clones with getting mods, though. That is a safety thing to me.
Hope helps.
Attys i'm fine with clones. Electronics i want an authentic.
