Have many years of experience with nasal showers (also from Emser). The redesign is a bad design. Does one mild to moderate pressure on the bottle (as in the description given), falls the lower blue part from and the content pours into sink and not in the nose :-( The complaint at producer brought me Although a replacement, this However, know the same defect. Lt. Manufacturer operator error from me. Ah yes. Can also be insufficiently clean through the small openings. No buy recommendation!
