I didn't check the Alexa integration because I don't have them integrated with Alexa.
I bought these to replace all switches in a bathroom I'm remodeling. The level locks are a beautiful design and make installation easy. When using 2 or more side-by-side, they fit together perfectly. I used screwless covers with them and they're so cool. They look great and install easily.
If I were to improve on the switches (and the receptacles which I also purchased) I would add the ability to add more than 1 wire to each locking terminal.
