I must say I have not regretted it. Has always been pretty heavy smoker. And it was worth a try. It works. With the steamer I have extremely reduced cigarette consumption. I'm still at 2 per day. The system works quite well. Ok, when filling one gets palatable hands. But that's all steamers more or less like that. What is slightly annoying - to get at the Gezuzel little throughout the day. That seems to be the reason the two devices are in the package. The Liquid containers is already relatively small. Otherwise a really good steamer which also is not too big and you can always have.
