I got my Digiflavor Drop RDA from Heaven Gifts a couple weeks ago and I've been loving this RDA. Build quality is really good, everything fits snug. I love the build deck, very easy to build on and works great for single or dual coils and has a nice deep juice well. The airflow is very smooth and quiet, easy to adjust and flavor has been outstanding. It works great as a dual coil RDA, but I've been using primarily as a single coil squonker and have been very happy with it.
