Auntie Ann, this filler is the only one I use. It's simple, and as long as I don't overfill the cart, no leakage. One pad lasts forever ! I use the generic version as well (mine come from Dollar General). No discernable taste or odor from the filler for me, but I can't really comment on the binder aspect; guess I wasn't aware it was present. This filler cleans easily and retains its shape fairly well. I've been using it exclusively for about 4 months now, and my first pad is still about 2/3 of the size of the original. I just eyeball the appropriate size, cut with scissors, and stuff it in the cart. Couldn't be easier !
