I ordered 3 boxes of bicomponent LED lamps (6 lamps total). They were received 12-6-7 p.m. In the evening the electrician came to install them. Unfortunately, the very first one he installed didn't work. This particular packaging box had less bubble wrap than the other two. The other five lights worked very well. Basement when full of daylight. I received a return QR code from Revain and returned a device that didn't work. In general, while the purchase is satisfied. A non-working flashlight I returned was replaced within 4 days. It was good . It works well. Overall, I'm happy with the customer service from Fantasy and Revain LED lights.
