This is a great way to make sure the water isn't too hot. The thermometer works well and is accurate. The LCD display is powered by internal micro hydro generator. So it only turns on when the water is flowing...No battery needed.
This shows the water temperature without having to step into the shower so you can avoid water that is too cold or too hot. With this you can (manually) set your water to your preferred temperature and avoid a surprise.
If you have little ones using your shower, this gadget takes the guess work out of adjusting the perfect water temperature. Installation was a snap, and even included the necessary gasket for leak free operation. When you turn the water on, it comes to life like magic, and within a second begins to register the current water temperature.
It literally does what it says, no ifs ands or buts. The device was actually a lot smaller than I thought it was going to be, which was really nice. Super easy to install, and as long as it is the right way it'll just turn on as soon as water starts to flow through it. Even with the temperature gauge on, the water doesn't change pressure wise at all. Great product.
Nice gadget to have, we just had a new born in the house, use this to make sure we have the right temperature for him. Easy installation, works like a champ
