Great quick response on the chat with my questions.

Great product. Integrates perfectly with SmartThings if you have Zigbee. Great to be able to integrate it directly with the SmartThings hub so it's not dependant on the internet connection. Easy to install if you're comfortable with a little bit of plumbing. Much, much better than valve motors that install over an existing ball valve.

Great product and service

Easy website to navigate and shipping was very quick.

Very Affordable and Convenient Option for Controlling Water Heater. The first thing is the reasonable price, which makes it very attractive. Second, it's it simplicity and Home Automation integration with various platforms (Neviweb, Apple HomeKit, Samsung SmartThings, Amazon Alexa, Google Assistant, Hubitat and Home Assistant). Third, the installation is pretty easy to do, even if you’re not an electrician. It took me under an hour to install it, Definitely a recommended product.
