The problem I saw with the ZFM mod, and I imagine with this derivitive of it, is that when the reservoir is down to only partially full it is dependant on the angle of the ecig to maintain contact between the fluid and the bridge. It's fine if the ecig is either horizontal or with the batt side angled slightly downward, but not with the batt side angled slightly upward. If you're aware of this and compensate for it, it's not a problem, and can even be a positive by giving you a little flow control over it.
Now if you're able to eliminate the bridge with your direct tube idea, it would still be angle dependant, but that's less of a problem because now you're going to a full manually controlled system of drip delivery, and the angle would be a simple part of that process since you're already consciously controlling the flow as needed. For drippers, this may be the best thing since sliced bread, but for someone looking for a "set it and forget it" solution, this is moving further in the opposite direction and probably wouldn't be for them.
Please correct me on any misconceptions I may have.
Also, how clean or leaky is it to top-off on liquid through your check valve if there's already some liquid in it? It doesn't leak any as soon as you break open the valve? Or is it only intended for empty refilling?
