Horrible Smart bulbs, have A really hard time keeping them synced together with the Sylvania smart home plus app or the Sylvania Bluetooth app And that’s just name a couple I’ve tried multiple. Emailed the company because there’s a warranty they have not reached out but once and that was to relay the message to someone else in the company. Since have switched to hue bulbs by Phillips. They may cost more but so much more worth it. All around will never purchase another Sylvania again. Poor customer service. poor communication, and poor products!
