I have been using the ce2 fluxomizers and when they are working and not leaking they are great. Problem is they were all leaking. I have read great reviews on the boge and ordered a box of the 2.0 for my ego. A friend of mine bought a box of 3.0 for her kr808 and gave me a couple to try on my ego because I have an adaptor. First, they are really hard to fill the first time, does that get easier when you top them off. Second I'm not getting much vapor, th or flavor from these, could that be because the ohm is to high or do these things need have to have a breaking in period. Any answers you could give would be great. Thanks in advance. Just hoping the 2.0 are good when they come in.
