I guess you did not read the entire thread from UR in the UK.
If you read the rest of the thread you will see the issue was caused by people connecting high voltage devises to the wrong port, even though each controller came with a warning label to make sure correct devises were connected to correct ports, and also it was mentioned in the manual.
So what GHL did to stop users making this error and blowing up their ProfiLux was to put a thermal fuse cut out inside all controllers, low and behold since then not one single issue
Sometimes it is hard to compensate for such user errors
but least profiLux stopped future user mistakes in its tracks.
The person who actually tried to make a big deal of this also from what I gather was the distributors of a competitors brand.
AQ is actually nearly $200 more expensive than GHL
http://www.aquariumobsessed.com/ AQ $799

ProfiLux $599.00CAD
If you are still looking into the AQ best to take a good look at the RC forum to learn all what is happening and get user feedback, just as I would suggest with GHL or any other controller.
