What makes these two not the same? Is it how much e-juice they can hold? I have a few MT3 and they are great ..... when they are working right. When they start flooding it really sucks. I have some RBA's and know how to rebuild coils and I've watched the u-tube on rebuilding the coils on these but I just can not get any of them to work right. They always flood out. Are the EVOD's better and don't have this problem? Or are the just smaller MT3's?
