Currently vaping on a Eleaf Ijust S and loving it. The problem is the cost of coils and cleaning the device whenever I want to test my DIY e-juice. So I am looking at getting a box mod with a RTA & RDA. RDA to test my DIY e-juice since it is easier to swap out wicks when trying different juices and RTA so I can make my own coils. Been looking at the Eleaf Ipower 80w TC 5000mah box mod. Any input regarding this box mod would be appreciated as well as what BUDGET RTA & RDA to get.
