Twisp Edge Coils NOT lasting and Leaking

Towards the end of May after almost R1600 spent on two Twisp Edge devices for both myself and my fiancee, we have been less than impressed! Both him and I up to date has been through 2 coils each. (6-8 weeks per coil? I think not). We do not overfill (his has been leaking liquid into his mouth), I also have waited for the coil to get soaked before use. It goes well for about a week then it starts to give that burn taste - coil never goes dry. Also seems 'tight' like not enough air is coming in. I've played around with the adjuster but it's not helping much. The battery life is also quite disappointing, at least with the Clearo it would almost last a whole day. I'm wasting liquid - which at R160 a bottle is not acceptable, also I'm not even tasting the liquid which seems weird (have been using Blueberry and Polar Mint). I have also spoken to a friend of mine who had the same issue with hers leaking, she eventually had hers replaced. I unfortunately don't have an additional R1600 lying around. I thought this device would be an improvement but to date it has been quite a disappointment.<br> <br> Melinda
