The EHPro Dark Horse RDA is an amazing RDA with a few unique features. Like many other drippers, the Dark Horse has adjustable airflow and 3 posts for easy dual-coil and single-coil builds. When adjusted to maximum airflow, the Dark Horse pulls like no other RDA. It comes included with a wide-bore 510 drip tip as well as an enormous mouthpiece attachment for easy dripping and incredible airflow. What really sets the Dark Horse apart, however, is the massive post holes; they're easily the largest of any RDA to date. You should have no problems fitting multiple strands of 24-gauge, or thicker, wire through the terminals! This RDA is sure to please the insatiable cloud-chaser within you!
