I've brought these a number of times now,we keep coming back as they're so good. Mum has 10 to 15 puffs of an evening, shortly after she is a chilled and ready for sleep. The flavours she says are good,they charge super quick and last for months. They're so good I've put a freind onto them. He now is a convert. We had one issue with the vape was faulty, was exchanged no problem.royal mail made it a problem, saying it was prohibited item,it wasn't the post office was just being difficult, so I used another post office. We were sent a replacement immediately.
