Was so eager to try this R80 cause I have always loved your products and have been getting into pods lately.
Let me start off by saying its an amazing concept. I love that I can use a dust capped pod at work and then switch over to the 510 and use my sub ohm tank. Very innovative and the design is awesome, looks great.
Unfortunately you guys put the fill port at the bottom of the pod. Not a good idea as liquid does seep through the rubber gasket slightly.
Also big con is the coil leaks very badly getting the connection/ magnet area full of E juice as well. Very disappointing and also very dangerous for the use of the external 18650 battery.
The coils are leaking through the adjustable air flow portion of them if it sits for more than a few hours.
Suggestion is definitely put the fill port at the top and also design a way for the press fit coils to not leak perhaps by removing the airflow adjustment on the coil.
Hope this helps as I want to see and purchase more great products from you in the future!
