Review on eufy by Anker Plug-in Night Lights, Warm White LED, Dusk-to-Dawn Sensor, Bedroom, Bathroom, Kitchen, Hallway, Stairs, Energy Efficient, Compact, 6-Pack by Patricia Rubio

I have just received an order for 6 eufy Lumi plug-in night lights. I really like the product, but unfortunately 2 of the 6 light bulbs didn't work in a completely darkened room. The only way to get those bulbs to glow is to put a piece of tape over the sensor. The light didn't come on when the room was completely dark. The doors were closed so no ambient light came in from the other room. There was no lighting from the devices to which the light is assigned (computers, alarm clocks, phones, etc. have been removed). The 4 working lamps were EXCELLENT. In fact they were in places where there was more ambient light than 2 lights that didn't work at all. I would really like 6 bulbs (not just 4) that work great, which unfortunately I don't have yet. Waiting for a response from the company to see if they back up their product and fix the 2 indicators not working.
