I became interested in vaporizers in 2007. I looked at the then available butane powered vaporizers and thought that I could make one that is healthier and faster operating. Three years and 12 prototypes later the first Lotus was ready to sell. I thought then that the Lotus was perfect and couldn't be improved. Now I realize that there is no perfect model and that the Lotus will always be improving. I hope you enjoy the present versions.
