Product works as advertised. App is easy to install and use. I can say this was the easiest shower head I’ve installed. You will hear a little hum while you are using it. This is probably the impeller spinning in the shower head. This is a quite hum and it dose not bother me, it just surprised me at first. The blue tooth works well, but I wish it was Wi-Fi. I need to have my phone in or near the bathroom for it to work. Now it will update past shower data, if missed, the next time the phone is near when you take your next shower. If it was Wi-Fi it could link to my network and my phone could be anywhere in the house. I would put this on the wish list for product improvement. This aside the product is great.

Easy to save water, if that is your goal. For a large household, this would be a lifesaver. I found out that I prefer a shorter shower at a cooler temperature, and since I have been using this instead of taking baths or long showers, I’ve been saving an immense amount of water. Our water isn’t expensive but in a lot of the country, there’s a water shortage, and in the rest of the world water can be expensive. If you are trying to have your family cut down on this app can be interesting feedback on how many gallons they have saved right away.

Hai has saved me many gallons of water per shower already and it looks great in my bathroom. A very handy device that helps cut down on unnecessary time spent in the shower. I love the light notification that tells you when your shower is at the desired temperature!

Picked up this shower head on sale. I’m a nerd for stats and this thing provides! I love being able to monitor my usage stats and I should be able to save a ton of water. The hydro turbine to charge the device is really neat!
