This might be perfect. And the button is easy to use
They have the manuals for both the Poldiac and Nanos on their site and they give all the details of these
mods. There are also some videos.

One heads up on the Nanos is that you have to lock it before you sit it down. But locking it is just a "flick" with your finger, so easy.
The Poldiac on the other hand is locked by rotating the "shirt" (outer sleeve around the button housing) to prevent access to the button.
Check out the OverOne
rda that they make. To me it is by far the best dripper ever made. 8mm deep
juice well, totally leak proof when you fully close the air flow control, a very unique way of adjusting the air flow. It can not be used as a single coil and that is why the name is OverOne, more than one coil.
