I am currently retaining liquids in my bambino bianco with a bambino booster. I can hardly wait until these are gone, will never buy bambino biancos again or the bambino boosters. So far the entire case of bambinos I purchased all have pinholes(some large enough to stream if gotten too wet), and I need to use these in public. As for their boosters, I recently tried the total dry maximum boost ups and they blow the quadro away(I use these at night).
