Been using Ego T & C system with juices like Bodas Bounty (100% VG) since the new year and loving it ever since I found a solid fix for the leaking issue. Recently bought a Provari with Ego thread adaptor and discovered the joy of variable voltage. So I pretty much abandoned the Ego battery (saved as emergency backup) and use the Ego tank/cone/atomizer/base portion on my Provari with thread adaptor. What I thought was bad atomizers turned out to be the bases not working (I have 4 sets which I switched heads with atomizers until I figured it out). They seem like a simple part but I have 3 out of 4 now that do nothing. Like there is a broken connection. Is there a known issue with my set up (Provari with Ego set up)? Do the bases go bad? Is there another choice? The only methods I find as satisfying but not convenient is direct dripping into Ego high resistance atomizers & drip tip; cartomizers have a funny taste, waste juice, and are hard to fill with 100% VG. I bought a surge tank, but that thing is HUGE. Any advice is well appreciated. Thanks.
