Twisp - Very disappointin with the product quality

Hi Twisp, <br> <br> I bought a brand new Twisp edge from the cresta kiosk on the 21/03/2016. <br> The smoothness didnt last very long though, I did everything according to the book and demonstration from the kiosk representative (while filling, putting back the atomizer head), <br> <br> 3 weeks passed I started getting a burnt taste in my mouth, so I changed the atomizer head, although it seemed to soon to change it. <br> At first it was still tasting burnt, but went away within a few minutes, then again 2 days later Im getting a burnt taste again... Why is the product quality so bad... <br> <br> I thought Twisp was a better quality e-cigarette, Im very disappointed ... wont be buying another Twisp product nor advise anyone to buy.
