Purchased 2 of these back in September just to try out a smart bulb. I liked the idea of not having to connect to an extra hub device. So wifi and HomeKit compatible were a must. Connecting to HomeKit was smooth and just worked. Siri commands are logical and work accurate to what you ask for. Brightness is a lot better than similar priced bulbs and the colors are amazing. I typically like desaturated warm tones for the evening and the bulbs can do exactly that. Every now and then I may have a connection problem and will have to physically turn the switch on and off. But it is very minor and far in between.
I liked them so much that i bought 2 more.
Waiting for more advanced HomeKit smart bulbs to come out, but for now, these do the trick!
