These smart switches add a different level of style and taste to your home! They functionally work great and just as good as any other smart switch, Except they are one in a kind for a smart switch that has the tempered glass design with 2 gang and 3 gang switches that actually get larger with the larger gang. Which is very important in the US where we have larger size switch boxes for larger gangs. So literally this is the only smart switch in the glass plate style that can be installed to replace a typical regular US 2 gang or 3 gang switch where all that is needed for install is to wire in the new switch (and no drywall work to make the gang box smaller is needed). So the additional cost of these switches compared to others, is definitely worth it considering the cost you would incur just to make those other switches fit where your existing regular switches are already installed. Not to mention, the Iotty design is so much more elegant than those other glass plate smart switches anyways. I am about 3/4 of the way in replacing all of my old regular switches with Iotty switches in my home. Regardless if it makes a lot of sense or not to have a smart switch at each location, I just love the way they add glamor to my home!
