Obviously there's been much thought, research and effort go into creating the Z-Biip and I'm impressed with the refilling system. It is far superior to other AIO's available at the moment. My only gripe with this would be the side fire button, I find it hard to press it as I have small hands and a touch of arthritis. I wish they had a front fire button as well. Coils are excellent, great vapour production and the flavour is amazing. On the whole pretty happy with it, but I do hope they bring out a larger tank eventually (from what I read online it's a possibility).
