One light is fantastic easy to set up the other light has a major glitch it only blinks slowly so therefore not able to connect it to my smart device on my phone I had my boyfriend who is a IT tech guy and he could not get it to connect as the light bulb only flickers in slow motion in the manual it needs it to blink fast when you're connecting I will order another one because I think the idea is fantastic I get the stuff can happen once in a while it's okay
