This is really an awesome idea but i think some precaution are recquired as the product consists of two parts, a tooth brush and a sound unit.
#The sound component must be installed in a high position where water cannot wet it.
#In the event of the toothbrush not being in use for a long time while the battery is inserted, battery leakage could damage it, so it is advisable to remove the battery for separate storage when not in use for a long period.
#After brushing, the head should be washed thoroughly in running water and kept in a dry place.
#Do not boil it as the bristle head may become deformed.
#When there is no noise from the sound unit, check whether the battery is inserted correctly, and if there is nothing wrong, try replacing the battery with a new one when a recording is not successful, and replace thebattery in the sound unit.
#The sound unit must never be allowed to get wet. The manufacturer will not be held responsible if the product is damaged by allowing it to get wet.
#When the product cannot function during normal use by the consumer, it will be repaired free of chage by the manufacturer or place of purchase within the warranty peirod.
#The purchaser must however pay forrepairs in the event of breakage due to negligent use or natural disaster.
#The warranty period shall be for a period of one year from the date of purchase.
