At about $12 a pop, I've got 5 of these filled with various juices. So far, no issues such as leaks or funky taste. I like the look and with the carto that's matched to the
juice (number of holes related to the mix and thickness), I am getting damned good performance. Plus they hold a significant amount of juice. So far, I've always forgotten to make a note of how much it takes to fill them when I am filling.
"Too eager to get back to
vaping", is my excuse and I am sticking with that.
