Back in my Merlin Mini, a couple of people mentioned that the iJoy EXO RTA is something that I should be looking at. So I placed an order at a local retailer and have been using it extensively for the last 10 days.
In short, you guys were right! The iJoy is simply phenomenal and has dethroned the Merlin as my favorite tank to date! It excels in both single coil mode as well as dual coil mode. The short configuration offers a bit more flavor but the same can be had in the tall mode by upping the wattage a bit.
Overall, 2 solid thumbs and thank you guys so much for directing me to this tank!
