There are not many videos if any on the Opus, so everything in here is from my sole experience and information from the Vendor. This has quickly become my GOTO mod for leaving the house! It never fires in my pocket, never dies on me in the middle of the day (Which was a concern being 1200MAH with a Variable Wattage Device) I love this mod, and if you have the money to get one and this is your "Taste" then I definitely recommend it to you.
