We stand by our lifetime warranty on all lenses and 2-year warranty on all other parts.
Every month we suggest removing dust and salt spray from the top of the device using a damp cloth. Cleaning out the condensation inside grooves on top of the unit with an air compressor on low setting is also good practice every 6 months.
It is suggested to always have ample ventilation for your power supply. Try not to push up close to any metal or wood and try not to cover with anything.
External fans or extraction of heat is always welcomed.
