Had original purchase for about a year and a half and still going strong, got another one about six months ago also good, now buying a third. I like having the choice of colours to suit mood and light level required, and it’s great being able to turn lamps on and off from phone, especially useful when out.
I bought two of these bulbs, the functionality is really great, options for colour, warmth, fade in and out, timer, schedule etc.. however the first one started flashing and then failed after about 4 months and the second one has just failed in the same way a week or two later.
Definitely wont be buying again
