I've tried plenty of boosters, these are my observations of the ones ive used so far.
The abena Abri-let Maxi boosters are ok:
They start out thin and swell a bit, are longer than most other boosters/run the length of most diapers and fit nicely between the leak guards of just about any adult diaper.
Just get the Maxi, not the regular and you'll be fine.
The tranquility boosters(both the standard and contour) aren't super great but help a little:
Thin but Soft, wick wetness pretty well, dont swell a ton, and for me I've had the issue of them bursting and sap getting out.
The Large NorthShore boosters are pretty good:
Start thin and swell quite a bit, wick well, wont burst easily, have an adhesive strip to hold it in place and are of decent length and with for adequate coverage.
The Rears boosters are my current favorite and work great for me:
Start out thick and fluffy and swell a ton, sweet scent and wick well.
Certainly worth a try, imho.
The ABU Powerups are decent but basically like the old Quadros from Bambino:
They swell a lot, have an adhesive strip, don't burst easily and a very wide pad.
The Totaldry Ultimate Boostups are pretty good:
Start out sorta thick and fluffy and swell a crazy amount, hourglass shape to fit better between your legs, adhesive strip, but unfortunately have the problem of bursting from time to time.
Still a good booster though.
Haven't tried the new and improved Quadro boosters from bambino, but the old Quadros were pretty decent though so if the new Quadros are improved then I'd say they're def worth a try, especially the new Quadro "Deluxe" which sound pretty crazy absorbent.
