Query: Illmatech Slide Dimmer - ill dsigned

Bought a new home with a dozen of these installed by the builder. High end switch however the cover on the push button portion has broke on 1/2 the switches in the house in 3 years. I have even had one that I replaced break for a second time.I cannot find a replacement cover for the push button switch, which would be a $.50 fix. Frustrating with a product that should last many, many years.
