It's getting annoying that I can't use all juice in the tank because of the high located holes in the newer RBA's.
Was the old one with the holes at the bottom good?
I'm thinking to order the old one, does it worth it?
The first RBA had tiny notches at the bottom, as @aerospace mentioned, people were dremeling them to be able to use high vg juice.
The original RBA Plus is my fav version: large holes at the sides, slightly towards the bottom.
Then came the RBA Plus V2, with tinier holes, causing dryhits with hi-vg / hi-wattage (i might have to adjust the wicking to prevent that, didn't try that yet).
Now there's also the RBA for the toptank with even smaller and higher positioned holes.
I made a pic of the 3 versions for the STM, left to right: RBA, RBA Plus, RBA Plus V2 (comes with all new STM's):

Here's the RBA plus next to the toptank RBA, notice the even smaller (and higher positioned) holes:

I just ordered a few of these: SKU 2551300 only for the caps with larger holes, the rest seems to be rubbish.
