My only thought with the eBarons is rebuilding the coil. I've never had a device with the ceramic part in the middle, and the space in there looks MIGHTY small.
Are they easy to re-wrap yourself? I prefer a .6-.8 ohm coil, and by the looks of it, it's going to be quite hard to wrap a coil yourself for it.
Also, I like drippers that can hold upwards of 20 drops...I see it says only 15ish drops DRY. Hmm
