It started last year in January. I bought a KTS that incorporated many GG ideas, as I am very frugal and wanted to find out if I liked that style of button, etc. It lead me to want the real thing, from the inventor of these sweet devices. I am now the happy owner of a GGTB, circa 2010. It was conceived and constructed before I started vaping. My GGTB is exactly what Imeo said it would be - inexpensive, simple, slim and light, with a button that is smooth as butter. I now know that once you use a GG, you understand the difference. It has soul. I will be vaping it for my three year anniversary as a vaper in a couple months. I know Imeo has had many great ideas since, but this is still an excellent one!
