Without getting into hot debate

and I write this as gentle banter
Show me a thread, a report anything where it shows a GHL ProfiLux controller has failed due to manufacturer fault

odd component maybe even though thats rare.
Sorry I dont mean in any way for that to be taken as hit, jibe or anything else just wanted to have a level debate

.
Lastlight - dont get hung up on roller numbers in dosers, the GHL doser has medical grade components, the amount of rollers has nothing to do with reliability, but the quality of the components used. I am not saying another make mentioned is unreliable, I am in no position to judge or comment but dont disregard a product just because it has less rollers, look more at the functionality it offers and client feedback of that product. And prices have not gone up
In regards to the controller comparison link. The Author is a long standing Aquatronica user that also helps with the support side on RC
we have asked the author countless times to update this for the profiLux but still has not done so, we do ask ourselves why?
