Review (2/5): Not the same pump as pictured
The dispensing pump was not the same unit as pictured in product page. While it did screw onto the Listerine bottle the threads didn't feel right and the cap sits at a slight angle indicating it's cross threaded. The screw collar itself was much shorter (1.5cm) than pictured (approx.. 3cm). The liquid pickup tube was 5cm short of reaching the bottom of standard 1.5L Listerine bottle.
In summary I believe the wrong pump was sent.
