Great device. The 21700 gives me all day vaping and the tank produces great flavour.More than sturdy enough for me on site all day.
I waited along time for this device as it could take the 21700 battery, and it’s well worth it. It’s a good, well made sturdy device with a good bulk and easy to hold. Zeus tank has a nice smooth drag and coils are affordable. I’m a heavy vaper but not into the world of different Devices, would really recommend this one to all who want to upgrade from their basic device. It’s like your second home...just more affordable.
