This is an expensive, luxury product. No one really NEEDS this, but man is it awesome! We were doing a bathroom remodel and decided since we were gutting the shower anyway we might as well add something cool like this. We love smart home items and this device seamlessly works with Alexa. The app seems pretty easy and is very intuitive. The interface that’s in the shower is great too. All-in-all, a very well-done unit that I would recommend to anyone that is changing out their shower. Be advised, though, unless you’re changing all of the tile in your shower and ready to completely remove the normal shower valve and retile your shower then this is the unit for you. If you’re just looking for an easy upgrade to your shower with minimal work, then you should look for something else.
