On 1/2 tread the o-ring groove/channel is slightly wider allowing the o-ring to slide further and on the other 1/2 the o-ring cutout groove/channel is cut too deep , so the o-ring is flush with the acrylic surface, making it not providing a watertight seal, and the acrylic edge presses against the vinyl when you tighten the clip. As a result of these issues, I ended up with water on the label. So skip this product and instead pay a few bucks more for one of the other well-reviewed offerings here at Revain.
