I have the RBA and adapter on order. I'm not excited, but will see.
Since I got the Mega PCC for my Eroll, it's my go-to.
Maybe the RBA will make this amazing difference that you all talk about. The concept rocks, I think it's just that the form factor doesn't do it for me. After the Eroll, I tend to reach for the Istick with a BCC Mega.... I want the Egrip to be the be all and end all, but I don't think it's going to happen.
It's not the fault of the device, I just enjoy the replication of smoking.
