I have some clearomizers from madvapes and some black steel ones from vaperite. I haven't tried the steel ones yet, but I've been using the clears for a while now. I'll never go back to regulars after using CE's, world of difference. One issue I've noticed. Both of the types I have look to be made by Royal Smokers. Anyone else run into quality control problems? I had two out of the ten clearomizers I purchased be DOA right out of the sealed package. I opened up one of the dead ones to see what was wrong with it and I can see wires completely missing. Two out of ten dead is really poor quality control for any product.
