Works almost flawlessly. Large following.
Why would you want to change?
I agree , the crown sets the standard and is what i still choose over everything else . The RBA option is incredible also.
The crown II is an outstanding tank as well especially if you have it's incredible RBA option .
Some like the Rafael RBA for the Crown II and it does work perfectly but imo the best RBA for the Crown II is the below with the posts and Clapton coils.
The Crown D1 is by far the smoothest tank you will ever experience , nothing comes close and it is 100% leak proof . Coils last for weeks , no joke.
