Customer Reviews

The product is not exactly the same as in the photo. The connection box is turned and the water inlet is against the wall, so I had to cut and modify part of the acrylic to locate it. Otherwise it works perfectly, and it was the only possibility, because the model by which I have changed it is no longer manufactured.
