“I’ve been using Blu for years and find they work well for me. I’m not very adventurous with flavours and stick to the minty ones. The devices don’t last for ever of course and over time I find that they need recharging more frequently and I do need to invest in new ones. But at least the recharge time is swift. The other thing I want to praise is the excellent delivery time - order one day and receive the next - very impressive!”
