I've bought 15.

These are so amazing. I am disabled and it isn't easy for me or my husband who is also disabled, to go around multiple times per day trying to navigate around the house turning things on and off. But we do not have to do that any longer. We connected this to our Alexa with ease. The entire thing took about 5 minutes to set up. You have to download an app to get started but the step by step expressions make things incredibly easy to set up. We love them so much, I've bought 15 for multiple rooms in our house and I will be buying more for my parents and grandparents too.
