ReWick'D RDA/RDTA by Wick'D
ReWick'D's airflow inserts better as it is easier to remove and install. Instead of using screws to secure the airflow insert, we use o-rings instead. If you're wondering if the airflow insert will rotate overtime during use, it won't. There is a rounded square cutout same as the WICK'D to prevent the airflow insert from rotating.
