Great mouthwash, poorly designed liter bottle
The mouthwash itself is good. The pH, at 6.6 is the best of the leading mouthwash products. The problem is the 1 liter bottle. If you hold it with your hand on the front and back, the compression force needed to pick up the bottle will cause the bottle to squeeze in abruptly to the point where liquid spurts out the top.
