At first they weren't as flavorful as the regular BVCs I use in my Nautilus, Nautilus Mini and my standard size Beyond Vape Silo tanks, but after they get past a couple milliliter break-in period they seem to perform just as well, in my Silo Lite, ET-Ss and Vivi Nova-Ss, as the original BVCs did in my others. I think I need a few more weeks before I can make a conclusive assessment though.
