faulty coils

Bought a new Edge - not impressed - the device leaked and was returned for a new Clearo. The coils - I have had problems with the older ones - was told they were faulty, and that a new supplier had been sourced. These new coils are even worse - don't last even a couple of days. Very disappointed - have been happy with Twisp for the last year, but looks like Twisp have gone to inferior suppliers and are sacrificing quality for cost. Twisp surely must take note of the numerous complaints - they are losing customers and this should be a worry? I will be looking for another alternative brand ASAP.
