I bought this yeelight bulb to give light at home when I want to distract my dog in case I come back late. You can turn it on with Yeelight App even from work. The various colors create different atmosphereI really like this. I 've been using it for a short time and at the moment I can't find any defects except some connection problem with the wifi. But I still don't know if it's due to my phone company or to the lamp. Yes, it's a good product.
