Transparent body is a big plus. I didn't have a key and the default key doesn't work. Look at it up close. When I depressurize water splashes everywhere but that's not a problem because it's outside but expect to get wet. Otherwise it works fine. The water pressure in the house is normal. 4 years later it works great. Don't buy expensive filters as it doesn't matter. I've changed my rating to 5 stars as it's very durable and still clean despite our crappy water.
