I ordered two bulbs direct from Teckin but they were not delivered by the courier.
This was a courier issue and not a Teckin issue.
Teckin was extremely helpful in trying to resolve the issue.
The support from Teckin is the best support I had from any business.
One of my light bulbs stopped working so I ordered a replacement. The company neglected to tell me the light bulbs have been changed. So the new bulb color does not match my other 3 in the front of the house. It looks stupid. I'll be ordering a new set of 4 from elsewhere.
Works great, syncs with Smart Life and Google Home. 👍
