Ok so I'm a die hard Cisco 306 user for dripping. But for 5 bucks I had to give these a try. And I haven't been disappointed. I was turned to these after another ECF member compared them to the HH357 and was also impressed. The one I have on now tests at 1.7ohms and I'm running it at 3.7v. I can get about 6-8 drops in these without a single gurgle or leak. Yes I have had ZERO leaks from these. I've ran both 100%vg bobas and pg/vg juices through this atty without a hiccup. I'd say it has a fairly light draw but not too airy and produces vapor as good as if not better than my Cisco 306's. I've been on one atty for going on 2 weeks and it's still burning like new. For some reason I also find going from juice to juice with these doesn't leave much residual flavor. Even after vaping some coffee flavors I can put in some bobas or gandalf and by the 2nd or 3rd hit the coffee flavor is gone and the new flavor is spot on. On the contrary I have a single 306 that is my "coffee atty" because I can't seem to get the coffee flavor out of it no matter what I do. If you like dripping definitely give these attys a look. They work by having 3 holes in the bottom that allows the liquid to seep down to the wick.
