I was able to download the app and connect with our router.   The adhesive strip doesn't seem extremely tacky, but time will tell.  It comes with four mounting clips if your surface isn't perfect.  If you follow the instructions, you shouldn't have any issues.  Obviously, the light strip isn't designed to adhere to rough, uneven, or dusty surfaces. You can use the light strip without WiFi, but it will have limited functions.  You can add voice control using Alexa, Siri, or Google assistant.  The light strip is dimmable and the lights can be white or multiple colors.  Lots of possibilities.
