The EHPro LB may not look like much, but this is one incredible dripper! First and foremost, this is the first EHPro RDA to include a truly wide-bore tip. By default, this RDA has a delrin insulator that will accept any 510 drip tip, and will come included with a stainless steel wide-bore drip tip. However, you can remove the insulator and replace it with a huge mouthpiece that's reminiscent of a drip cap. This mouthpiece will greatly increase your airflow and vapor production, as well was make it much easier to drip directly through the mouthpiece, and eliminates juice backup completely. Under the hood, you have a 3-post design with huge post holes, which is great for thick-wire builds. The deck is deep and will hold 10-20 drops of liquid without leaking. The top cap has 3 airflow slots, so you can choose to have 1 slot open for single-coil builds, or 2 slots open for dual-coil builds. Each of these slots can be adjusted by simply rotating the top cap. Lastly, the top portion of the cap screws in and out for easy cleaning and dripping, and eliminates that crooked look you sometimes see with RDAs that use an O-ring. This RDA has wide-open airflow unlike any other RDA before it, so if you're looking for clouds, this is the RDA you need.
