The review you are referring to doesn't offer much in the way of details surrounding their usage and situation. A description of how it is leaking is not even given. Considering there are only two places which the product could leak, the entry point and the emptying point, various factors could be coming into play. Such as the user not screwing on the emptying cap correctly or tightly. Also, overfilling the URSEC Urinal can cause leakage at the entry point as the anti-reflux funnel only works up to the fill level.
