Rebuilding it, compared to an AGA-T or RSST...
No comparison.
It is a completely different animal.

First off, the coil/wick is upside down. Meaning... it hangs from the top of the tube (right under the drip tip) with the wick pulling from the bottom container. Which can be removed, cleaned/refilled without messing with the wick/coil.
You just have to feed the ends of the wicks back into the bottle.
Basically, I would not recommend this one to a novice.
But, IF you don't mind tinkering a bit, it can be a nice little hybrid.
