I was very satisfied and had bought 5-6 of these cases for various filters. They all looked very good, until at some point (probably due to heat), the pressure in the network increased and it broke, causing many problems. Fortunately, it was in an outdoor area. Under a balcony, deep inside, so that it has no direct contact with sunlight. I have connected 3 in a row inside the house in one case and 2 others outside in another house, where the problem occurred. To avoid having the same issue again, I bought a pressure reducer, which is quite expensive. There is a possibility that the increase in pressure did not come from the network but from the solar panels, in which case, because the pressure reducer is installed at the inlet of the filters, the same problem may exist. Time will tell.
