I'm stress test my equipment too much to use clear tubes again. Tell me how they hold up to drops or sneezing or breathing heavy by them will yah? Still have fresh memories of the failomizers.
Well, I put mine to the test. Got it pretty hot several times and the tubes held up. So far so good. No warping or melting. I was vaping hubby's ProVari at 4.8V. I don't think I would go higher due to the tubes. I also used one on my Prodigy V3.1 at 3.7V. Excellent taste, vapor, and TH.
