These work great. I have noticed a tiny quality issue (unevenly drilled holes, my FIRST DOA atty was in a box of the LR Drip-o-Mizers, and a strange taste in many of them). But they do work and work very well. The vapor production is quite wonderful, and when you get a good one, you know it. The taste is smooth, crisp and clean. My boyfriend is hooked on them.
I've moved on to more expensive atties, but these are really great for the price.
