I am not sure how old my second hand Aromed 4.0 is, but it still works like the first day i received it! Since it comes with it's own small bubbler you will need adapters to get it to mate with your bubblers. I use some high temp two part silicone material to make adapters. I still break mine out sometimes to give it a rip but the Herbalizer, EVO and Nano rule the roost! Flavor on the Aromed is amazing though! EDIT: Just broke it out again to test something out. It works best with the supplied small bubbler. I tried my larger bubbler with it but it was not nearly as good! And yes it still works like the bomb!
