Bought a complete set while they were on discounted price, had an electrician install them all, needs a slightly larger hole than regular switches. Very easy to pair and piece of cake to control with the app. Very difficult to setup with google home due only to the naming and level of time required, but thats not because of anything to do with this product.

Only minor and very minor downside is that a 3 lamp light is not recommended for a bedroom as the glow ruins the dark...view more
