I own two of their Tanks and am happy with them. I have a 115g that has been up and running for close to 3 years now, a 67g in my garage awaiting it's day. Both appear to be well built tanks. No complaints at all. I picked mone up at their facility, and saw where and how they were built. Pretty interesting, and they definately do enough volume that you'll hear if anyone had a problem.
