Installation is fairly easy, but I had to add a seal (not supplied) on the cold water inlet as there was a huge water leak even squeezing hard.
After several days of use, I find that the temperature is well regulated and that, quite quickly. The factory setting is 38 °.
With this type of product, there may be a slight loss of pressure even opening fully.
The right trigger secures the temperature and it is essential because buttons turn very easily.
The left trigger for the volume of water is unnecessary in my opinion because no shower is with a trickle.
The metal above the mixer is warm enough on the side of the hot water supply.
Cleaning is easy.
A test over time ...
