The performance of the waterproof case generally depends upon its usage. The O-ring of the waterproof case or the underwater housing may wear off due to the repeated opening and closing of the case cover. It is recommended that the waterproof case be replaced once a year, depending upon the frequency of use and storage conditions. It is also recommended to apply the designated grease on the O-ring to maintain the waterproof performance.
If you have a splash-proof model, it is recommended that the packaging be replaced by an authorized repair shop once a year.
