Very convenient and ideal product to protect the sleep of parents ... For cons the setting is very easy and the wrong diet connection quickly becomes faulty, the result must be repeated all settings several times a week !!! The bulbs have a lifespan of one year and a half / two years but it is impossible to find these bulbs in trade: the product is good for the trash. In short the price is very high for a lifetime of 2 years maximum while the product is not a technological feat.
