Stopped working after less than a year

Bought this back in fall of 2018. Worked good for a while and then started making my lights flicker and would take a really long time for the lights to turn on. Had to finally replace it with a new switch (different brand) and my lights are no longer glitching. One thing I never liked about it was that the wall plate was too lit up and I had to cover it to sleep because it was too bright.
