I'm generally pleased overall with the bulbs, but have been having ongoing issues with connectivity.

They keep switching from Bluetooth to Thread and when this happens, there are delays in operating the lights with Apple Homekit and Siri. I use with iPhone and Home Pod Mini that is always connected and in the same locations. Sometimes the lights will not respond requiring a reset, other times I have to reboot my Apple Devices. A bit annoying, but I'm hoping these issues are resolved going forward.

The Customer Service Team are excellent though. I have had a great experience with resolving an issue with one bulb which was replaced.

I would still purchase these again as I am sure the issues are down to the underlying connectivity that involves Apple Software as well as the bulbs.

I love my Shapes, Essential Light Bulbs and Light Strips. My flat has been transformed into a colourful, joyful space!

Couple of issues with the bulb.
You CANT control the bulb if your not close to it UNLESS you have a HomePod or Apple TV set up on the network. so don’t bother automating it to turn off when you leave the house or when you arrive because you will be too far away for a connection to your phone.
The bulbs firmware has been on 1.2.13 and I’ve tried updating it 4 times but that doesn’t seem to work (still in 1.2.13 wants 1.6.41)
But other than that it has some nice scenes.
Maybe look at some other ones on the market.

The lighting is good however unfortunately the connection to the product is very poor. I spent hours trying to pair to the light holding different devices right next to it until it finally decided to pair, only for it to tell me I needed to update the firmware. So of course I followed that process and the update would get to around 3 percent even after leaving it 'updating' for long periods of time next to the bulb just to say some sort of error connecting and to 'try again'. I am quite upset with this as there seems to be no way for it to ever work the way it should, I could never get it to pair with Google home either, and while in the app trying to turn it on and off and change colour/brightness etc (which is good on the rare occasion it works) however loses connection even while device is right next to the bulb. Not worth the time or the hassle by any means.
