After 4 months of use only in the shower it started flashing so I think I will need a new one. Haven't tried returning or exchanging it yet, not sure what warranty it has. The seller replaced the defective unit for free, great seller, but the replacement unit failed less than a year after installation. the same symptoms as the first. Started blinking. It is only used when taking a shower, and then not always, since there is enough natural light during the day. The product is not of good quality.
