yeah the 72 used to leak cause the guy that was putting on the silicone was doing it all wrong. They have since fired him. I would let the batch sell for a while and then get one. The 90 is pretty cool however. I just got finished instaling one in a wall. the 92 is real cool also. Most of my clients like it cause you can see it but it is out of the way and you are not going to bump into it.
