Okay,
I am completely ready for any abuse this post may inspire
But
I have found my favorite topper.
I own a bunch of CE4s, a bunch of Evods, a bunch of mini protanks (with and with/o removable mouthpieces) and one Davide.
So I do have reference points.
My favorite topper BY FAR is this weird thing that FT calls a CE 5. It is NOT a CE 5 by any definition I can find but it works like a charm.

NO leaking
NO threading problems
Lasts FOREVER.
Very very inexpensive.
I love the warm vapor and the reliability.
My favorite to date.
Wickless ?? (I wonder if there is mesh or ??? in the tube?) and non rebuildable , but perfectly reliable and (imo) does NOT mute flavor.
very inexpensive and NON Fiddly.
Just my opinion
feel freely to disregard.
