I am becoming more glad by the minute that I did not order the GSA-M. With all the CC and debit card problems, the flooding and filling issues... I think I'll just stick to my GSAs.
I know I complained about flooding at first, but it seems to have stopped. I did turn it up to 13W (need to keep it under 15 to maintain my Tootle Puffer status) and no more flooding. My regular Air flooded on me at low watts and it also stopped when I upped it to 13. It could be my tight draw really sucks the juice into the coil.
I have several needle nose topped bottles that have no issue filling the M. Haven't tried a dropper.
Only issue for me now is the pool of juice after removing the base. I am going to tilt the tank after inverting and before removing base to see if that clears most of it.
Liking my M way more and more every day and will probably love it after I replace the drip tip with a Nautilus tip.
