AP is a nice vape, my list of things that could be better on it is
1. Look at top cover / cap its too thin can be a pain to get a grip on to refill. Not a major issue but could be better.
2. Look at the locating lugs on the deck, again too thin could be a lot easier to line up if they had a bit more depth to them. Sometimes you think its lined up and it won't screw all the way down so you know it isn't which brings me to ...
3. If the deck isn't lined up right and you have to adjust it into position its a faff to rotate it that 1mm more because there is nothing to hold on to that is not round. So once you know that - you can use the juice flow holes to help line it up right, it could of been easier.
4. Air flow ring is a little spinny - would of been nice if it had detents to stop it at fully open / closed.
5. JFC is if anything a little tight and trying to move it can unscrew the atomiser from the mod instead or close off the airflow as well.
None of these things are major, it's a good atomiser. It is not better or worse than the MF it is just a different device. It certainly has great vape qualities and so does the MF so do a lot of others....that's why we all have so many different ones. If any of them were perfect we would only have that one wouldn't we
