Not sure on the specific heater since I haven't used it but titanium heaters tend to be pretty durable and reliable. They are less prone to breaking and don't have the issue of sudden temp change (i.e. being out of water for a water change) causing breakage that glass ones do.
Also, Catalina gets high marks around here for their lighting systems as being very high quality.
I'm not sure if you're aware of all this and are seeking specific reviews of the product or this kind of general info was what you were seeking, but I hope it was useful.
