Pretty good all considered
We installed a prodigy 3 from Bunnings in 2010 after old unit broke down on the weekend. We are a four person family but can have up to 7 with relatives staying. We always had good, strong hot water even though certain family members have very long showers!
Standard maintenance items are thermal relief valves and anodes every 5 years.
The gas regulator failed a couple of years ago which meant pilot kept going out and this was about $150 I think from one of the plumbing shops.
Ours was within a few weeks of the 7 year tank warranty when...the tank started leaking, but Dux still warranted the replacement which I was pretty happy with. We had to pay for the plumber to do the install, but they fixed some issues with the previous install and upgraded it to the prodigy 4 star at the same time. I can't comment on the issues others are having but the plumber seemed to think you should get 15-20 years from these units if you keep the maintenance up. For the life of the tank it is critical that: 1) the relief valves are regularly tested and replaced - these do fail and if they don't open properly they will cause tank to burst
