Those of you who were unfortunate enough to receive an IPV Mini where your tank/RDA/RTA/etc does not sit flush with the device... i found a solution. An hour ago I accidentally knocked my mini off the work bench in my garage and while inspecting it for damage, noticed that my damn aerotank v2 was no longer flush with the top. So i opened it up and took a good look at the 510 connector and it was now slightly higher than the top and discovered the manufacturer "Press-Fit" it into place. So I put the side panel back on to ensure the frame stayed ridged, applied a couple pieces of blue painters tape to each end to protect the finish, and carefully put it in my bench vise and squeezed it just a bit and the connector was once again flush with the top. If you somehow push it down a bit too far, just install your vaping device on it and tightening it should bring it back up flush.
So those of you who are handy with tools can save yourself the headache of having to send your mini back and wait for a new one.
