The HATTY RDA is deffinitly a coil builders dream. This RDA has a velocity style deck with 3mm post-holes making the coil oppertunities endless! You can install anything from a simple build to the biggest exotic coils you can think of. The HATTY RDA has an enormous liquid well so you don't have to worry about those dry hits as often. This is a 3 piece RDA with a locking barrel and a threaded on chuff style top cap which can be replaced with a 510 drip tip adapter. The 510 connector is gold plated and adjustable so you can use it on any device you chose, even a hybrid mod! The dual bottom airflow on the HATTY offers a great combination of flavor and vapor production.
