My review from the altsmoke.com website(slightly revised - to protect the innocent)
Title is: Calling this a mod is an insult:
When I think of a mod I think of someone modifying a peice of copper or aluminum pipe or PVC they bought at Home Depot , adding threads, painting it and epoxying to it a CNC'd aluminum adapter(that they got by ripping apart an old joye 510 battery). This is not to offend any modders out there, if that's your thing, more power to ya. But if you're gonna make something commercially available and throw a somewhat hefty price tag on it, it better be more then a high school, vo-tech, metal shop project.
Getting back to the Silver Bullet, This is NOT a mod by any definition. This is a well engineered, form following function, aesthetically superior, work of art. Just look at it , run your fingers over it and feel it, press down on the switch and feel the quality of the firm click. But most of all, Vape with it, and you will find it miles above anything else available out there.
