Phil, I tried these and was pretty disappointed. I could get a couple of good hits but then it dried out quickly. If I wanted to try and drip down the tube to get liquid on the coil I could get another decent hit or 2. I took 1 apart to see if I could make it wick better by opening up the slot/hole a little. Then all the juice just ran in and flooded it. It seems like a good concept that could be made to work if implemented properly. The wick only goes just to the hole in the cone inside. I would think that if the wick actually went into the reservoir area and had a bigger hole in the cone inside it might show some potential. For now these go to the back of my rainy day supplies. For now I'll stick with the LR DCCs from MadVapes. They work great and my only complaint is longevity. But at $1.80 each it's not too bad. Someday I may try the Boge 2ohm that is your benchmark just to see if I'm missing something. Keep up the excellent reviews! I've enjoyed them all.
