Twisp aero

Bought the top of the range twisp - thinking it would be problem free, as I was told by the sales person! I bought it asking if the twisp would leak liquid, I was assured by the sales person that no twisp would leak and that this aero is the best of the best.. Using the coil that came with, 20mins into vaping the coil already had a gurgling sound, spitting small drops of liquid in your mouth as you smoke... So, I was dissapointed but I could live with that.. Then upgraded to the free flow 0.5 ohm coils, which is great, or it was - untill i realized that these coils only seem to last maybe 2 refills??? Then you get this disgusting burned taste, I mean really!!! I was told I would get weeks out of each coil... My '****' twisp I bought from the liquir store - which was cheaper altogether than only the coils of the twisp still lasts and that was used extensively! I am sorry! I am utterly dissapointed, and wont recomend twisp to any person out there! I really think this is unnaceptable, especially when you specifically ask about the product and about the stories you hear - then being 'corrected' by the sales person and being assured that your buying quality! Turns out the jokes on me!
